22. Female elephants remain in their mother=s herd, while male elephants are ejected from the herd to lead solitary lives after they reach sexual maturity. A wildlife biologist wants to know if these solitary males have a different survival rate compared to females. Assuming an equal number of male and female elephants at birth, we expect the proportion of males among mature elephants to be (P = 0.5), if survival rates are the same as females. The wildlife biologist obtains gender data for a sample of n = 86 elephants from a very large population in southern Africa; and 36 out of 86 were males. Given this information, describe the sampling distribution of the sample proportion p= proportion of males in the adult age class in a sample of this size, under the assumption that the nevia survival rate for males elephants is the same as for females. ento . Describe the sampling distribution Bing evioom of by scaling the X-axis for of the curve to the right. Shade the area under =[0 =X19 this distribution that corresponds to the probability of getting p
