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 Complete parts a through d 2 2 2 4 2 12 4 2 4 4 4 12 12 2 12 4 12 12 a Find the value of the population variance o 18 667 Round to three decimal places as needed b Find the variance of each of the nine samples then summarize the sampling distribution of the variances in the format of a table representing the probability distribution of the distinct variance values Probability Type integers or simplified fractions
