A) Solve the following problem on its own sheet of blank paper. Santos works in a suburb of Detroit and is studying the weekly salary for a basic office worker. Santos takes a random sample of 33 office worker weekly salaries. The sample has a mean of $422. Assume the population standard deviation is $58. Based on this sample, construct a 99% confidence interval for the true population mean of the weekly salary of an office worker. Do not use StatCrunch. Show all formulas used, work and steps.
