Question

Home Runs Two random samples of professional baseball players were selected and the number of home runs hit were recorded. One sample was obtained from the National League, and the other sample was obtained from the American League. At =α0.05, is there a difference in the means? Use the critical value method with tables.

Use μ1 for the mean number of home runs from the National League. Assume the variables are normally distributed and the variances are unequal.

State the hypotheses and identify the claim with the correct hypothesis.

H0:  Claim or not a claim

H1: Claim or not a claim

Is this Hypothesis test a one-tailed or two-tailed test?

Find the Critical Value(s): round to 3 decimal places

Compute the test value: round to 3 decimal places  z=

Make the decision

Summarize the results

8 2 9 2
6 5 6 8
American League
