Conduct a One-Sample T Test in SPSS®

Open the Week 6.sav file in SPSS. The variable data (VAR401k) included in this file represents the average annual 401k investment information you gathered from the sample of employees (N= 300) in your organization.

Perform a One-Sample T Test procedure using SPSS. Note: This procedure can be found under the menu item, Analyze > Compare Means.

Results from the SPSS Analysis:

401K% N = 300, Mean = 10.47, Std. Deviation 5.912, Standard Error Mean = 0.341

One-Sample Test Test Value = 0

401k% t = 30.678, df = 299, Sig. (2-tailed) = .000, Mean Difference = 10.471, Difference Lower = 9.80, Difference Upper = 11.14

Make a decision and interpret the results:

1. What is the p value?

2. Describe how ou determined the p value:

3. Interpret your results (ie., Will you reject the null hypothesis? Why?)

Explanation / Answer

1. P-value = 0.000
2. The p-value is the level of marginal significance within a statistical hypothesis test representing the probability of the occurrence of a given event.

3. Here P-value < alpha 0.05 so we reject H0
Thus we conclude that the average annual investment from the sample of employees is not 401k
