23. Normal temperature The researcher described in Exercise 19 also measured the body temperatures of that randomly selected group of adults. Here are summaries of the data he collected. We wish to estimate the average

(or “normal”) temperature among the adult population.

a) Check the conditions for creating a t-interval.

b) Find a 98% confidence interval for mean body temperature.

c) Explain the meaning of that interval.

d) Explain what “98% confidence” means in this context.

e) 98.6F is commonly assumed to be “normal.” Do these data suggest otherwise? Explain.
