Red Blood Cell Count A simple random sample of 40 adults males is obtained, and the red blood cell count (in cells per microliter) is measured for each of them, with these results: n=40, x= 4.932 million cells per microliter, s=0.504 million cells per microliter ( from Data Set 1 "Body Data" in Appendix B). Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 5.4 million cells per microliter, which is often used as the upper limit of the range of normal values. Does the result suggest that each of the 40 males has red blood cell count below 5.4 million cells pern microliter.
