1. Student Intern wishes to see whether the pulse rates of track student athletes are different from the pulse rates of the weight-lifting student athletes. He selects samples of 100 track athletes and 100 weight-lifting athletes. The results are shown here. Can the student intern conclude at alpha = 0.05, that the pulse rates of the track student athletes is different from the pulse rates of the weight-lifting athletes?
   1. Track-Athletes - Sample Mean = 90, Sample size = 100, Population Variance = 25
   2. Weight-lifting Athletes - Sample Mean = 88, Sample size = 100, Population Variance = 36 Use the steps below to test the difference between the two means.

a. State the hypotheses and identify the claim.

b. Find the critical value.

c. Compute the test value.

d. Make a decision.

e. What type of error is being committed based on your results in d.

f. Summarize your results.
