Moviegoers The average "mowegoer" sees 8.5 movies a year. A moviegoer is defined as a person who sees at least one mowe in a theater In a 12month period. A random sample of 50 moviegoers from a large university revealed that the average number of movies seen per person was 9.9. The population standard deviation is 3.2 movies. At the 0.05 level of significance, can it be concluded that this represents a difference from the national average?

She thinks that the mean is higher. So she selects a random sample of 28 applicants and asks each how many medical schools they applied to. The mean of the sample is 8.8. The population standard deviation is 2.6. Test her claim at a = 0.01. Assume that the variable is normally distributed.

Sick Days in Bed A researcher wishes to see if the average number of sick days a worker takes per year is less than 5. A random sample of 30 workers at a large department store had a mean of 4.8.

A local cable company canvassing the town to promote a new cable service found that of the 299 households visited, 231 had two or more television sets. At a = 0.01, is there sufficient evidence to conclude that the proportion is less than the one in the report? Do not round intermediate steps.
