A social scientist wishes to conduct a survey. She plans to ask a yes/no question to a random sample from the U.S. adult population. One proposal is to select 100 people; another proposal is to select 900 people.Which of the following is true regarding the sample proportion p̂ of "yes" responses? The sample proportion from the sample of 900 is more likely to be close to the true population proportion, p. The sample proportion from sample of 100 is more likely to be close to the true population proportion, p. The sample proportion in either proposal is equally likely to be close to the true population proportion, p, since the sampling is random.

The town council recognizes that responses from households with pets may be different than those from households without pets. According to the survey, out of every 50 households, 15 have no pets and 25 have exactly 1 pet. Based on the survey responses, if a household in the town is selected at random, what is the probability that the selected household has more than 1 pet?Responses 1050Answer A: the fraction 10 over 50A 1550Answer B: the fraction 15 over 50B 3550Answer C: the fraction 35 over 50C
