A city is interested in building a waste management facility in a certain area. One hundred randomly selected residents from this were asked, "Do you support the city's decision to build a waste management facility in your area?" Of the 100 residents interviewed, 54 said no, 4 said yes, and 42 had no opinion. A large sample z-confidence interval was constructed from these data to estimate the proportion of this area's residents who support building a waste manage facility in their area. Which of the following statements is correct for this confidence interval?





A) This C.I is valid because a sample size of more than 30 was used.


B) This C.I is valid because each area resident was asked the same question.


C) This C.I is valid because no conditions are required for constructing a large sample C.I for a proportion.


D) This C.I is not valid because the quantity n(p-hat) is too small.


E) Not valid because "no opinion" was included as a response category for the question.

n(p-hat) too small for "yes"





n(p-hat) = 100*(4/100) [not] %26gt; 10
