Question

A genetics experiment involves a population of fruit flies consisting of 2 males named Carlos and Danny and 2 females named Erin and Fran. Assume that two fruit flies are randomly selected with replacement. a. After listing the possible samples and finding the proportion of females in each sample, use a table to describe the sampling distribution of the proportion of females. (Type integers or fractions.) b. Find the mean of the sampling distribution. mu = (Round to two decimal places as needed.)

Explanation / Answer

probabilty that 0 females selected =(2/4)*(2/4)=1/4

probabilty that 1 females selected =(2/4)*(2/4)+(2/4)*(2/4)=1/2

probabilty that 2 females selected =(2/4)*(2/4)=1/4

a)

b)

therefore mean =0.5

proportion of females(x) probability P(x) 0 1/4 0.5 1/2 1 1/4
