Question

Normal temperature The researcher described in
Exercise 11 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) 98.6°F is commonly assumed to be “normal.” Do these
data suggest otherwise? Explain.
