Please explain how I determine this for part B

The data in the table represent the ages of the winners of an award for the 43 past ve years. Use the data to answer questions (a) through (e). 30 33 (a) Compute the population mean, u. p = 41 (b) Compute the mean for all 502 = 10 samples with size n = 2. Sample Sample Mean Sample Sample Mean 43,53 48 53,46 49.5 43,30 36.5 53,33 43 43,46 44.5 30.46 38 43,33 38 30,33 31.5 53,30 41.5 46,33 39.5 (c) Construct a sampling distribution for the mean by listing the sample means and their corresponding probabilities. Give all the unique sample means in ascending order. (Type N if there is no solution.) Sample Mean Probability Sample Mean Probability :0on |_ll_l|_l|_ll_l |_ll_l|_l|_ll_l
