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

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 ultraviolet light, whereas the second group was not shaded from the sun’s ultraviolet light.  The researcher believes he can demonstrate that the 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 hypotheses

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