Researchers determined that 52 tissues is the mean number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold:sample mean = 60, standard deviation=22. Calculate the value of the test statistic to test Ho: u = 52 versus H1: μ≠52 at a = 0.05.
