To the right are the outcomes that are possible when a couple has three children. Assume that boys and girls are equally likely, so that the eight simple events are equally likely. Find the probability that when a couple has three children, there are exactly 2 boys. 1st 2nd 3rd p boy - boy - boy boy - boy - girl boy - girl - boy boy - girl - girl girl - boy - boy girl - boy - girl girl - girl - boy girl - girl - girl What is the probability of exactly 2 boys out of three children? Type an integer or a simplified fraction.)

Use the population of {37, 29, 24, 13} of the amounts of caffeine (mg/12 oz) in four beverages. Assume that random samples of size n=2 are selected with replacement. Complete parts (a) through (c) below. a. After identifying the 16 different possible samples and finding the mean of each sample, construct a table representing the sampling distribution of the sample mean. In the table, values of the sample mean that are the same have been combined. Probability Probability 37 25 33 24 30.5 21 29 18.5 26.5 13 (Type integers or fractions.) b. Compare the mean of the population to the mean of the sampling distribution of the sample mean. The mean of the population, is the mean of the sample means, (Round to two decimal places as needed.) c. Do the sample means target the value of the population mean? In general, do sample means make good estimates of population means? Why or why not? The sample means V the population mean. In general, sample means make good estimates of population means because the mean is estimator.
