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.
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.
