A random sample of 36 textbook prices is taken from a local college bookstore. The mean of the sample is x= 72 , the sample standard deviation is s = 24, and the population is normally distributed. Construct a 90% confidence interval for the mean price of all textbooks in the bookstore

Sixty-four randomly selected adults who buy books for general reading were asked how much they usually spend on books per year. The sample produced a mean of $1450 and a standard deviation of $300 for such annual expenses. Determine a 99% confidence interval for the corresponding population mean. (Please show all the steps)
