Problem Set 3.5: One-Samplettest in SPSS

Criterion:Calculate a one-samplettest in SPSS.

Data:Riverbend City online news advertises that it is read longer than the national news. The mean for national news is 8 hours per week. The following sample of the Riverbend City online news readers is: 5, 7, 6, 2, 4, 8, 5, 4, 18, 21, 8, 7, 4, 5, 6.

Instructions:Complete the following:

1. Enter the data from Problem Set 3.5 into SPSS and name the variable asTime.
2. In theToolbar, clickAnalyze, selectCompare Means, and then selectOne-SampletTest.
3. SelectTime, then clickArrowto send it over to the right side of the table. In the box labeledTest Value, enter8.
4. ClickOKand copy and paste the output into the Word document.
5. State the nondirectional hypothesis.
6. State the criticaltfora = .05(two tails).
7. Answer the following: Is the length of viewing for Riverbend City online news significantly different than the population mean? Explain.
8. Based on the SPSS output, including a test value (population mean) of 8, calculate the 95% confidence interval.
9. You need to write the hypothesis as a sentence, specific to the context, and not using symbols.
10. Hint from professor: This problem is a challenging one. The SPSS program is not always consistent with what different values mean from one type of analysis to another. To improve, it is necessary to determine the proper way to use the SPSS output from the one-sample t-test to calculate the confidence intervals. This involves a hand calculation, so be sure to show your work. Hopefully this resource can assist you with navigating the challenges in this area.
