T = -3.15 describes the mental health variability. This is a significant value because it’s provides the degree of freedom. According to the data above the significance of a t ratio can be determined by comparison with the critical values in a statistical table for the t distribution using the degree of freedom for the study. The value is significant because p value of it is 0.002 which is smaller than alpha value set for this test that is 0.05 3. Is t = −1.99 significant? Provide a rationale for

analysis includes two tests. The first test conducted was a hypothesis test to determine whether the job-enrichment program changed the average output. The second test performed measured whether the job-enrichment program reduced the proportion of defective products. PHStat was used to calculate t-scores‚ z-scores and critical values needed in order to determine whether the program would be rejected. Results from the first hypothesis test determined that the job-enrichment program did not consistently

Using the chi-square formula we will calculate the goodness of fit to our expected ratio and our observed ratio when we determine and record our results.
