A German physician, Carl Wunderlich, measured temperatures from about 25,000 people in the mid 1800s and found that the average was 37 degrees Celsius. There is some evidence that the mean body temperature has been changing over time. Assume that the body temperature of adults is approximately normally distributed with a mean of 37 degrees Celsius and standard deviation 0.40 degrees Celsius. (a) [2 marks] What value of body temperature distinguishes the highest 10%? (b) [2 marks] People with body temperatures above 38 degrees are said to have a significant fever. Show that approximately 0 62% of people have a significant fever
