Conditions met --> Normal model --> 1 prop Z test. Z = = 3.1434. P(Z > 3.1434) = 8.352 x 10-4. We reject Ho b/c p-value of 8.352 x 10-4 is less than a = 0.05. We have sufficient evidence that the true % of people dying from cancer in Utah in 1955 is greater than 0.1364. Thus, there is evidence that the death rate from cancer among the movie ...

Neither test statistic is beyond a critical value. There is not enough evidence to reject either claim. On page 3.9, students are to use the 1-Prop z Test command (MENU > Statistics > Stat Tests) to find the P-values for each test. The P-values are about 0.55 (cats) and 0.17 (dogs), both above 0.10, the significance level.
