Consider the 24 values shown in the table. Complete parts a through d below. 9 25 22 27 28 14 8 9 31 23 25 21 8 23 21 16 7 28 33 The sampling error for the sample is (Round to two decimal places as needed.) ع 13 23 23 90 23 a. A simple random sample of 4 items is shown below. Calculate the sampling error for the sample. 9 9 21 23 The sampling error for the sample is (Round to two decimal places as needed.) b. If a random sample of n = 8 items includes the values below, compute the sampling error for the sample mean. 23 21 13 23 23 16 27 25 The sampling error for the sample is (Round to two decimal places as needed.) c. If a random sample of n = 12 items includes the values below, compute the sampling error for the sample mean. 27 25 21 8 33 9 9 13 16 23 22 25
