Lab: Hypothesis Testing of a Single Mean and Single Proportion

Module by: Susan Dean, Barbara Illowsky, Ph.D.. E-mail the authors

Class Time:

Names:

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=2σ=2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.

  1. 1. H o H o :
  2. 2. H a H a :
  3. 3. In words, define the random variable. __________ =
  4. 4. The distribution to use for the test is:
  5. 5. Determine the test statistic using your data.
  6. 6. Draw a graph and label it appropriately.Shade the actual level of significance.
    • a. Graph:
      Figure 1
      Blank graph with vertical and horizontal axes.
    • b. Determine the p-value:
  7. 7. Do you or do you not reject the null hypothesis? Why?
  8. 8. Write a clear conclusion using a complete sentence.

Language Survey

About 42.3% of Californians and 19.6% of all Americans over age 5 speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school that speak a language other than English at home is different from 42.3%.

  8. 8. Write a clear conclusion using a complete sentence.

Jeans Survey

Suppose that young adults own an average of 3 pairs of jeans. Survey 8 people from your class to determine if the average is higher than 3.

  1. 1. H o H o :
  2. 2. H a H a :
  3. 3. In words, define the random variable. __________ =
  4. 4. The distribution to use for the test is:

    • b. Determine the p-value:
  7. 7. Do you or do you not reject the null hypothesis? Why?
  8. 8. Write a clear conclusion using a complete sentence.
