Assume that two fruit ies are randomly selected with replacement. a. After listing the possible samples and nding 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.) I). Find the mean of the sampling distribution. p = (Round to two decimal places as needed.) C. Is the mean of the sampling distribution [from part 03)] equal to the population proportion of males? If so, does the mean of the sampling distribution of proportions always equal the population proportion? O A. Yes, the sample mean is equal to the population proportion of males. These values are always equal, because proportion is a biased estimator. O B. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is a biased estimator. O C. Yes, the sample mean is equal to the population proportion of males. These values are always equal, because proportion is an unbiased estimator. O D. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is an unbiased estimator.
