Suppose we think more newborns are boys. Our SRS has 13,173 boys out of 25,468 newborns.

Suppose we think more newborns are boys. Our SRS has 13,173 boys out of 25,468 newborns. If you do a hypothesis test to see if you have evidence that more newborns are boys, what will be your z test statistic?

1 Solution)Null hypothesis ,H0: p = 0.5Alternative hypothesis, H1: p > 0.5Test statistics = p^−p√ p∗q/n ~ N(0,1) P hat = (13173/25468) = 0.5172Test statistics = 0.5172−0.5√ 0...
