A Survey of 50 Companies

In January ‘08, fifty customers of a lumber manufacturer were surveyed regarding their satisfaction with products and service. These customers buy from the supplier and sell to retail chains like Home Depot and Lowes. Shortly after, the manufacturing company was sold. In June ‘08, the customers were telephoned and interviewed and were asked to rate overall satisfaction again.

Variables in the working file

For each research question below , describe in your Microsoft Word document the application of the seven steps of the hypothesis testing model.

Step 1: State the hypothesis (null and alternate).

Step 2: State your alpha (unless requested otherwise, this is always set to alpha = .05).

Step 3: Collect the data (use one of the data sets).

Step 4: Calculate your statistic and p-value. (This is where you run spss and examine your output files.)

Step 5: Accept or reject the null hypothesis. (This is where you report the results of your analyses t (df) = t-value, p = sig. level.)

Step 6: Assess the Risk of Type I and Type II Error. (Did the data meet the assumptions of the statistic, effect size, and sample size?)

Step 7: State your results in APA style and format.

Question 1 : How do small companies compare to the major competitor?

The trade association magazine published a report that this company’s major competitor accounts for about 60% (60.0) of their small customers purchases. Is this company’s Usage different than their competitors?

3. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance.

Question 2: Is there a difference between small and large companies in their overall satisfaction with the company as rated in January?

1. Run an independent samples t-test.
2. Use size as the independent variable.
3. Use overall satisfaction in January as the dependent variable.
4. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance.

Question 3 : Has satisfaction with the manufacturer changed since the change in company ownership?

1. Run the paired samples t-test
2. Use satisfaction in January and satisfaction in June as the variable pair.
3. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance.
