A survey asked the question ""What do you think is the ideal number of children for a family to have?"" The 434 females who responded had a median of 2, mean of 3.46, and standard deviation of 1.01.
Answer parts a-d.
a. What is the point estimate of the population mean?
b. Find the standard error of the sample mean. standard error = (Round to three decimal places as needed.)
c. The 95% confidence interval is (3.37, 3.55). Interpret.
A. We can be 95% confident that the mean number of children that females would like to have is between 3.37 and 3.55.
B. We can be 95% confident that a given female will want between 3.37 and 3.55 children.
C. Ninety-five percent of females want between 3.37 and 3.55 children.
D. We can be 95% confident that the proportion of females who want children is between 3.37 and 3.55.
d. Is it plausible that the population mean μ = 2?
A. Yes, because 2 falls outside the confidence interval.
B. Yes, because the median is 2.
C. No, because 2 falls outside the confidence interval.
D. No, because the sample mean was not 2.
