A simple random sample of 52 adults is obtained from a normally distributed​ population, and each​ person's red blood cell count​ (in cells per​ microliter) is measured. The sample mean is 5.25 and the standard deviation is 0.67. Use a 0.06 significance level to test the claim that the sample is from a population with a mean equal to 5.4, which is a value often used for the upper limit of the range of normal values. What do the results suggest about the sample​ group?  Show all your work on paper. Enter a critical value with 2-decimal places. show formulas and draw all curves.
