Student learning outcomes
The student will select the appropriate distributions to use in each case.
The student will conduct hypothesis tests and interpret the results.
Television survey
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that
σ = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.
