Question

A genetics experiment involves a population of fruit flies consisting of 1 male named Barry and 3 females named Courtney, Diane, and Elaine. Assume that two fruit a. After listing the possible samples and finding the proportion of males in each sample, use a table to describe the sampling distribution of the proportion of males. (Type integers or fractions.) b. Find the mean of the sampling distribution. mu = (Round to two decimal places as needed.) c. is the mean of the sampling distribution from part (b)| equal to the population proportion of males? if so, does the mean of the sampling distribution of proportions always A. Yes, the sample mean is equal to the population proportion of males. These values are always equal, because proportion is an unbiased estimator. B. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is an unbiased estimator. c. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is a biased estimator.

Explanation / Answer

b) mean = mu = 0*(1/16) + 0.5*(6/16) + 1(9/16)

=0.75

c) Correct Answer: Option (A)
