Question

A researcher is studying the hatching rates of two groups of Pacific tree frog eggs. One group of eggs was shaded from the sun's ultraviolent light, whereas the second group was not shaded from the sun's ultraviolent light. The researcher believes he can demonstrate that the hatching hatching rate for the shaded group is higher than the hatching rate for the exposed group.

	Sun Shaded Group	Unshaded Group
Total in Group	75	90
Total Hatched	47	41

Let P1 denote the hatching rate for the sun shaded group and let P2 denote the hatching rate for the unshaded group. The researcher will test the hypothesis

H0: p1 - p2 = 0 vs Ha: p1 > p2 at a 5%level of significance. Find the p-value
