Human body temperature is 98.6 degrees, a nurse thinks this is too high, that is the mean body temperature is below 98.6. The nurse obtains a random sample of 106 human body temperatures and finds that the mean for the sample is 98.20 degrees; she assumes the population standard deviation is 0.62 degrees. At an alpha=0.02 test the nurse's claim.
