64. Interpret a confidence interval: A survey organization drew a simple random sample of 625 households from a city of 100,000 households. The sample mean number of people in the 625 households was 2.30, and a 95% confidence interval for the mean number of people in the 100,000 households was 2.16 < μ< 2.44. True or false, and explain: a. We are 95% confident that the mean number of people in the 625 households is between 2.16 and 2.44. b. We are 95% confident that the mean number of people in the 100,000 households is between 2.16 and 2.44.
