Find the appropriate p-value to test the null hypothesis, H 0 : p 1 = p 2 , using a significance level of 0.05.
-A random sampling of sixty pitchers from the National League and fifty-two pitchers from the American League showed that 16 National and 11 American League pitchers had E.R.A's below 3.5.
A)123.710
B)0.680
C)10.184
D)0.884

Question

Quizplus · Accepted Answer

The p-value is calculated using a two-proportion z-test. The test compares the proportion of National League pitchers with ERAs below 3.5 to the proportion of American League pitchers with ERAs below 3.5. The calculated p-value is 0.680, which is greater than the significance level of 0.05, indicating that there is not enough evidence to reject the null hypothesis.
