The data I will need to test this claim are the sample size of both companies, the mean annual bonuses for both groups and the standard population variations of the annual bonuses

The hypotheses tests are given as:

H0: 1 - 2 = $100

H0: 1 - 2 > $100 (stated claim)

To do the hypothesis test, the following procedures are adhered to:

State the hypotheses and identify the claim as given above.

Find the critical value. At the given level of alpha, the critical value is 1.96

Compute the test value. Using the monthly means and the variance and standard deviation

Make the decision at the 0.05 level of significance.

Summarize the results:

Null Hypothesis (Ho)u1-u2 <30

Alternative Hypothesis (Ha)u1-u2>30

u1= population mean monthly benefit of workers

u2= population mean monthly benefits of disabled workers
