Use the confidence interval to find the margin of error and the sample mean. (1.70,2.04) The margin of error is. (Round to two decimal places as needed.) The sample mean is (Type an integer or a decimal.)

Find the margin of error for the given values of c, s, and n. c= 0.99, s= 2.7, n = 12 Click the icon to view the t-distribution table. The margin of error is . (Round to one decimal place as needed.)

Calculate the standard score (z-score) of the given sample mean. Round your answer to two decimal places. u = 23 and o = 7; n = 72; ī = 22

Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P 25 Click to view page 1 of the table. Click to view page 2 of the table. The z-score that corresponds to P25 is (Round to two decimal places as needed.)

Use the dataset below to fill in the blanks. The space between the data and the blanks isprovided so that you can show each data value's deviation and each data value's deviation squared.Sixteen families were selected at random and the number of children in each was recorded   0 0 0 1 1 2 2 2 2 2 3 3 4 6 8 12

Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P 48 Click to view page 1 of the table.
