A genetics experiment involves a population of fruit flies consisting of 3 males named Alfonso, Bart, and Carlos and 1 female named Debbie. 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? ⒸA. 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. 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.

fill in blank, there are only 3 options, decreases, increases or remain the same.

Find the mean, the median, and the mode(s), if any, for the given data. Round noninteger means to the nearest tenth. (If there is more than one mode, enter your answer as a comma-separated list. If an answer does not exist, enter DNE.) −8.5, −2.4, 4.7, 4.7, 6.4, 8.9, 9.9

Three randomly selected children are surveyed. The ages of the children are 2​, 4​, and 12. Assume that samples of size n=2 are randomly selected with replacement from the population of 2​, 4​, and 12. Listed below are the nine different samples.
