Assume That You Plan to Use a Significance Level Of \alpha

Assume that you plan to use a significance level of $\alpha = 0.05$ test the claim that p $\mathrm { p } _ { 1 } = \mathrm { p } _ { 2 }$ . Use the given sample sizes and
numbers of successes to find the z test statistic for the hypothesis test.
-A random sampling of sixty pitchers from the National League and fifty-two pitchers from the American League showed that 19 National and 8 American League pitchers had E.R.A's below 3.5.

A) z = 272.163
B) z = 2.009
C) z = 2.612
D) z = 22.404
