Moviegoers The average "moviegoer" sees 8.5 movies a year. A moviegoer is defined as a person who sees at least one movie in a theater in a 12-month period. A random sample of 42 moviegoers from a large university revealed that the average number of movies seen per person was 10.2. The population standard deviation is 3.2 movies. At the 0.01 level of significance, can it be concluded that this represents a difference from the national average?

Mathematics scores on the CBBC standardized exam are normally distributed with a population mean of 164 and a population standard deviation of 12. Ms. Norbury believes her two classes of a total of 48 students have a mathematics comprehension different than 164 and she decides to give her classes the exam. The mean on the exam was 161. Test to determine if her class' mathematics comprehension is different than 164 at the 0.05 level of significance. (Show all seven steps.)
Wheaties cereal is claimed to have an average of 3 grams of dietary fiber per serving. We want to test this hypothesis and to see whether we believe that is true or that the mean amount of fiber is significantly different from 3 grams. A random sample of 25 servings was taken and it yielded a sample mean of 3.4 grams with the sample standard deviation in the amount of fiber, s = .8 grams. %3D Assume that software has determined the p-value to be.02. Carry out the test at the 5% level of significance. Be sure to state your decision rule and your decision for the test. O Fail to Reject the null hypothesis since the p-value is .05 O Fail to Reject the null hypothesis since the p-value is > .05

Standardized tests: In a particular year, the mean score on the ACT test was 22.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 504 and the standard deviation was 100. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Find the z-score for an ACT score of 30.
