Question

A study asked respondents. "If ever married, how old were you when you first married?" The results are summarize (a) and (b) below (a) Use the summary to determine the point estimate of the population mean and margin of error for the confidence x= |21 850| (Type an integer or a decimal) E = (Type an integer or a decimal.) (b) Interpret the confidence interval A. There is a 90% probability that the mean age of people when first married 19 between 21.804 and 21.896 years. B. One can be 90% confident that the mean age of people when first married is 21.850 years. C. One can be 90% confident that the mean age of people when first married is between 21.804 and 21.896 years D. There is a 90% probability that the mean age of people when first married is 21.850 years

Explanation / Answer

Margin of error = z* SE = 1.64×0.028 =0.04592

And the right interpretation is c) i.e., we are 90% confident that the population mean will be between (21.804, 21.896).
