Identifying the indicated value using Statdisk

Data Set 2 in Statdisk (Body temp) includes a sample of 106
body temperatures with a mean of 98.20 F. Assume that σ is known to be
0.62F. Consider a hypothesis test that uses a 0.05 significance level to test
the claim that the mean body temperature of the population is less than 98.6F.

What is the test statistic?

What is the critical value?

What is the P-value?

What is the conclusion about the null hypothesis (reject,
fail to reject)?

Using results listed in Data Set 5 in Statdisk (Chmovie),
test the claim that the majority of animated children’s movies show the use of
alcohol or tobacco (or both). Use a 0.05 significance level.

3

Use the weights of the post 1964 quarters listed in Statdisk
(Coin Weights). Test the claim that the quarters are manufactured according to
the U.S. mint specifications that the mean is equal to 5.670g.
