Hi,

Can somebody please help me with the answer to the following practice question. Please explain the solution

320.2. Sixteen (16) financial institutions are surveyed. Their average overnight rate is 40.0 basis points with a sample standard deviation of 9.0 basis points. Which is nearest to the width of the two-sided 99.0% confidence interval (C.I.) for the "true" population mean overnight rate, where width of C.I. is upper limit minus lower limit.

Thanks
