I'm really looking forward to seeing you Wednesday night at the Kennedy center!
Reply:Kathy Grifin,


I know this guy whom I am communicating with through e-mail. He's young and wants to be a personal assistant. Can you tell me what it is that you look for in a personal assisstant? I will relay it to him today. He's 16, and I think that he could use help in the spelling department, but he's a good guy.





I'll post it as a question. Your input will be MOST appreciated. Thank you.

Reply:Mel Gibson might make a good personal asst. I hear he's looking for a job.
Reply:Liz is up and about now...saw her last night in Santa Monica..she did a great job at the Macy's benefit for AIDS....truly remarkable woman. She heads up the AAAAA list. And she has told me that she will come as my escort IF I decide to go. (Michael is now persona non grata at most of these affairs.)





Phil and Marlo, although off the lists by their own desire, have agreed that they will put in a showing if I call them 2 weeks before the event. It would be good to see them out and about, great people, the both of them





Oops! Word got out that Joan heard of Liz's escort offer, and now she is insisting on coming...don't even think about it! If I find out that either Joan or Melissa will be there, you will be crossed off our A list!


George Michael is available IF we pay for a cab afterwards to a downtown park after midnight...(I was the one who made the offer of the cab ride, his interest immediately peaked!)


Jennifer Anston is in danger of sliding off the A list, is dying for some positive exposure that has nothing to do with Brad Pitt or Angelina...she will come if the cause is AIDS... but she wants an escort, and has asked me to get a hold of George C...I have a call into him, his agent said he would be interested IF Jennifer will do the dead afterwards...I have a call back to Jennifer, but she is out right now...will get back to you on that one.


IF you screw up this event with your normal antics, I will send you to Joan and Melissa! And that is NOT an idle threat!
Reply:I got one for you to invite ... DOVIE BEAMS.... she is old but a hoot.. she brought down marcos and had amelda after her so she is always up for a good story or two and can bring a few good ppl with her.....

Math Help - Multiple Choice Question?

To estimate the number of people in Springfield, population 10,000, who have a swimming pool in their backyard, 250 people were interviewed. Of those polled, 66 had a swimming pool. How many people in the city might one expect to have a swimming pool? (Round to the nearest whole number, if necessary.)





a. 2640 people


b. 37,879 people


c. 264 people


d. 2 people

Math Help - Multiple Choice Question?
You know that 66 out of 250 people had a swimming pool.





That allows you to form a probability.





P(pool) = 66/250 = 0.264





To find expected value, mutliply probability times sample size.





E(pool) = P(Pool)*n


E(pool) = 0.264*10,000
Reply:A. 10000 * (66/250) = 2640
Reply:A. 2640


26.4 %
Reply:Answer is A.





250 interviewed people is 100% 66 of them have a pool. So that is 66/2.5= 26.4 (2.5 is 1%). Then you can assume that 26.4% have a pool. So 10000 is 100 % 100=1% times 26.4 is 2640
Reply:Just set it up like this 66/250 = x/10000 cross multiply and you get 250x = 60,0000. then divide both sides by 250 and you get A = 2640 people


Multiple Choice Math Question?

To estimate the number of people in Springfield, population 10,000, who have a swimming pool in their backyard, 250 people were interviewed. Of those polled, 120 had a swimming pool. How many people in the city might one expect to have a swimming pool? (Round to the nearest whole number, if necessary.)





a. 480 people


b. 4800 people


c. 20,833 people


d. 3 people

Multiple Choice Math Question?
OK -proportion





Of 250, 120 had a pool





So





120/250 = x/10000


.48 =x/10000


4800=x


Answer is b





Hope this helps.
Reply:It is like:





If from 250 people 120 had swimming pool..





That's mean 10000 * 120/250 = 4800 people.





Good luck!
Reply:(120 /250) * 100 = 48% of the participants have a pool.





So





10,000 * 48% =





10000 * 48/100 =





4800 people have a pool





Answer B
Reply:20,833 people
Reply:120/250=0.48 (proportion of people who have pool in interwieved person)


0.48*10000=4800 (estimated number in city)


solution is b.

So who can help me with a probability question?

so who can help me with a probability prob?


One hundred college students were interviewed to determine their political party affiliations and whether they favored a balanced- budget amendment to the constitution.





23 democrats %26amp; 32 republicans favors the amendment


25 democrats %26amp; 9 republicans do not favor the amendment


7 democrats %26amp; 4 republicans are unsure.


democrats=55


republicans=45


*A person is selected at a random from the sample. Find the probablity that the described person is selected. (You have to find part a, b, c... they are not answer choices!! :P)


a.) a person who doesn't favor the amendment.


b.) a republican


c.) a democrat who favors the amendment

So who can help me with a probability question?
a.) 34/100=34%


b.) 45/100=45%


c.) 23/100=23%
Reply:Er, I answered this a few minutes ago?

Reply:OK I think I could help you with your probability question(s)





The probability that the next 'selected' person is someone who does NOT favor the amendment is 34 out of 100 which rounds up to 3 out of 10. which then again rounds up to 1 out of 3 which is technically a third of all your sample range. This is the answer to question a)





Lets work this one out shall we? OK 100 peeps are still in the sample range. We know that 23 Dems and 32 Reps (abbreviations used) favor this amendment. so that's 55 (slightly half of the sample). Then we are left with 34 peeps (cross party) who does not favor the amendment and 11 (cross party) peeps who are undecided.





we know that 34 is a third of your sample range so the chances or probability of the next person to be chosen who does NOT favor the amendment is 1 out of 3. So the probability is a maybe.





OK second question. What are the chances that next chosen person is a Republican. OK lets look at the facts. Theres 32 Reps (abbrev.) in the Favor camp added to the 9 Republicans in the NOT favor camp and 4 that are unsure. Lets add them shall we? 32+9+4=45 which is the smaller half of the sample range of 100 peeps. lets quantify the values to simplify the equation to provide the formula. 45 is 4 or 5 out of 100 which downsizes to 4.5 out of every 10. So to answer your question the probability that the next person to be chosen is a republican (cross camp) is nearly half of the sample range or 1 in 2. so the probability is a strong possibility.





OK the last question. What are the chances the next person to be chosen is a Dem (abbrev.) who favors the amendment. We know from the sample range that the peeps are either Reps or Dems. And we know from my answer to question B that there are 45 Reps in the range out of 100 which leaves 55 peeps as Dems (we can tell by adding the Democratic representatives in each camp 23+25+7=55) which ironically reflects the Democrats composition ratio of the Senate. OK but we need to numerise the actual number of Dems who favors the amendment. we know that only 23 Dems favor the amendment. Lets downsize this. 23 out 100 is 2 out of 10 which is only 20% that 1 in every 5 or 1 Fifth. so the probability that the next chosen person is going to a Dem who favours the amendment is a weak maybe.





I hope my breakdown summary helps
Reply:a) 34/100 = 17/50


b) 45/100


c) 23/100
Reply:try using a simple table
Reply:a. person who doesnt favor the amendment =


no. of ppl not favoring the amendment/ total number.


= 34/100





b. republican = no. of republicans/ total number of ppl


= 45/100





c. there are 23 democrats that favor the amendment


therefore prob. of one of them being the person selected


= 23/total number = 23/100

Probability question 2?

2) A market researcher typically obtains answers from 1 shopper in 4. If 15 shoppers are interviewed:





a) What is the probability that nobody answers?


b) What is the probability that exactly 5 people answer?


c) What is the probability that less than 10 answer? (Use tables)


d) What is the variance of the number of answers?





Please explain how i would work these out and answers, i have an exam and i don't know how to work these out. Thanks in advance.

Probability question 2?
a) 3/4 dont answer. if 15 people don't answer


p(no one answers) = 3/4 ^15





b) p(5 people answer) - use binomial distribution.


15C5 * 1/4 ^5 * 3/4 ^ 10





c) p(%26lt;10 answer) = 1 - p(%26gt;=10 answer) =


1 - ( (15C10 * 1/4^10 * 3/4^5) + (15C11 * 1/4^11 * 3/4^4) +


(15C12 * 1/4^12 * 3/4^3) + (15C13 * 1/4^13 * 3/4^2) +


(15C14 * 1/4^14 * 3/4^1) + (15C15 * 1/4^15 * 3/4^0) )
