When games were sampled from throughout a season, it was found that the home team won 127 of 198 professional basketball games and the home team won 57 of 99 professional football games. At the 5% level of significance, does this indicate that there is a significant difference between the proportion of home games won by the two sports?

(1) List all the information necessary for conducting the hypothesis test and state which

test you are doing.

(2) State the null and alternative hypotheses and whether you would use a right-tailed

test, a left-tailed test, or a two-tailed test.

(3) Sketch the critical reason, indicating on the sketch what the critical value(s) are.

(4) Determine the calculated z or t.

(6) Decide if you will Reject or Fail to Reject the Null Hypothesis.

(7) Interpret your conclusion in terms of the problem.
