Carl Reinhold August Wunderlich?) reported body temperature, gender, and heart rate for a

number of subjects. The body temperatures for 25 female subjects follow: (15 points)

97.8, 97.2, 97.4, 97.6, 97.8, 97.9, 98.0, 98.0, 98.0, 98.1, 98.2, 98.3, 98.3, 98.4, 98.4, 98.4,

98.5, 98.6, 98.6, 98.7, 98.8, 98.8, 98.9, 98.9, and 99.0.

a) Test the hypothesis : = 98.6 versus : ? 98.6, using = 0.05. Find the P-value.

b) Check the assumption that female body temperature is normally distributed.

c) Explain how the question in part (a) could be answered by constructing a two-sided

confidence interval on the mean female body temperature.
