Data set (i), because it has more entries that are farther away from the mean. B. Data set (ii), because it has more entries that are close to the mean. C. Data set (iii), because it has two entries that are far away from the mean. Which data set has the least sample standard deviation? A. Data set (ii), because it has more entries that are close to the mean. B. Data set (i), because it has more entries that are farther away from the mean. C. Data set (iii), because it has less entries that are farther away from the mean. (b) How are the data sets the same? How do they differ? OA. The three data sets have the same mode but have different standard deviations and means. Compare the three data sets on the right. (i) 13141516171819 (ii) 13141516171819 (iii) 13141516171819 C.

The state test scores for 12 randomly selected high school seniors are shown on the right. Complete parts (a) through (c) below. Assume the population is normally distributed. (a) Find the sample mean. x = (Round to one decimal place as needed.) (b) Find the sample standard deviation. S= (Round to one decimal place as needed.) (c) Construct a 99% confidence interval for the population mean . A 99% confidence interval for the population mean is ( , ).
