Two hundred randomly selected residents in Hoptown were surveyed and asked, "Do you support the city's decision to build a public health clinic in your area?" A total of 108 said no, 8 said yes, and 84 had no opinion. A large sample z-condence interval, [5 :I: z * \"M , was constructed from these data to estimate the proportion that n support building the clinic. Which statement is true for the condence interval? (5 points) 0 A sample size of more than 30 was used; therefore, the condence interval is valid. 6) Each resident was asked the same question; therefore, the condence interval is valid. 0 Because there are no conditions required for constructing a large sample confidence interval for a proportion, the confidence interval is valid. 0 This confidence interval is not valid because the quantity np is too small. 0 "No opinionll was included as a response category for the question; therefore, this confidence interval is not valid
