a. What is the point estimate of the population mean? 3.38 b. Find the standard error of the sample mean. standard error = 0.082 (Round to three decimal places as needed.) c. The 95% confidence interval is (3.22, 3.54). Interpret. A. We can be 95% confident that the mean number of children that females would like to have is between 3.22 and 3.54. B. Ninety-five percent of females want between 3.22 and 3.54 children. C. We can be 95% confident that the proportion of females who want children is between 3.22 and 3.54. D. We can be 95% confident that a given female will want between 3.22 and 3.54 children. d. Is it plausible that the population mean μ = 2? O A. No, because 2 falls outside the confidence interval. B. Yes, because the median is 2. C. No, because the sample mean was not 2. D. Yes, because 2 falls outside the confidence interval.
