Auniversity is conducting a survey to study the number of hours students sleep at night during exam week. a sample of 20 students was drawn, and these responses were obtained: 6.5, 5, 8, 5.5, 7, 4, 4.5, 5, 6, 5.5, 4, 7.5, 6, 7, 8, 5, 6, 6.5, 6.5, 5. the standard deviation of the population mean is 2 hours. arrange the steps in the correct sequence to find the range in which 95% of the sample mean occurs. tiles the standard error of the mean of the sample is . the range in which 95% of the sample mean occurs is . the range in which 95% of the sample mean occurs is 5.93 + 2 × 0.45 = 6.83 hours and 5.93 − 2 × 0.45 = 5.03 hours. the sample mean is . the 20 students' total number of study hours is 118.5 hours. calculate the standard deviation.
