A genetics experiment involves a population of fruit flies consisting of 2 males named Alex and Bart and 2 females named Courtney and Dana. Assume that two fruit flies are randomly selected with replacement. 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. Proportion of males Probability 0 0.5 1 (Type integers or fractions.) b. Find the mean of the sampling distribution. μ=|| (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 equal the population proportion? OA. Yes, the sample mean is equal to the population proportion of males. These values are always equal, because proportion is a biased estimator. OB. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is a biased estimator. OC. Yes, the sample mean is equal to the population proportion of males. These values are always equal, because proportion is an unbiased estimator. OD. No, the sample mean is equal to the population proportion f males. These values are not always equal, because proportion is an unbiased estimator.
