A local pet shop is trying to determine what percent of the U.S. population prefers dogs to cats. Last week they surveyed the 274 people who entered the store. Of those 274 people, 183 people prefer dogs to cats. We will build a 95% confidence interval to estimate the true proportion of U.S. residences who prefer dogs to cats. First, however, we should see if we have met the normality requirement.

Which of the following correctly assesses the normality requirement?
a. We can assume a normal model since the sample size is considered LARGE ENOUGH (Since n = 274).
b. We can assume a normal model since the sample size is considered LARGE ENOUGH (Since (274)[.67)(1 - .67) = 60.6 and this is greater than 10).
