QUESTION 2 Given a set of 48 samples with a sample average of -11, and a sample deviation of 9.6, determine a lower bound on the population mean assuming a 99% confidence level. QUESTION 3 Given a set of 4 samples with a sample average of 0, and a sample deviation of 7, determine a lower bound on the population mean assuming a 90% confidence level

It is not asking to plug in the lower bound from the range of " upper and lower"

It is asking only to calculate a one sided

Thank you
