Question
You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals.
 
From a random sample of
47
business​ days, the mean closing price of a certain stock was
​$121.84.
Assume the population standard deviation is
​$10.38.
 
Interpret the results.
 
 
A.
You can be​ 90% confident that the population mean price of the stock is outside the bounds of the​ 90% confidence​ interval, and​ 95% confident for the​ 95% interval.
 
B.
You can be certain that the population mean price of the stock is either between the lower bounds of the​ 90% and​ 95% confidence intervals or the upper bounds of the​ 90% and​ 95% confidence intervals.
 
C.
You can be certain that the closing price of the stock was within the​ 90% confidence interval for approximately
42
of the
47
​days, and was within the​ 95% confidence interval for approximately
45
of the
47
days.
