Consider a data set which gives the body temperatures of a random sample of 52 healthy adults, reported in degrees Fahrenheit. The data was found to be roughly bell-shaped with a sample mean of 98.28 degrees and sample standard deviation of 0.68 degrees. Calculate the z-score of a body temperature of 101 degrees F and determine if this is an unusual observation. The z-score is -4; the observation is not unusual. The z-score is -4; the observation is unusual. The z-score is 1.02; the observation is not unusual. The z-score is 1.02; the observation is unusual. None of the above
