A survey was conducted to study the amount of sleep (in hours) that high school students get on a weekday. The following is the result of the survey for a random sample of 15 students: 5.5, 7.5, 7, 6.5, 6.5, 7.5, 6, 7.5, 9, 6.5, 4.5, 6, 6, 7.5,5 A. Find the range of the data. (Note: range is defined as the difference between the largest and the smallest observation). Range = B. Find the standard deviation of the data. Standard Deviation = hours Round to 2 decimal places. C. Interpret standard deviation you computed in part B. The average deviation of the amount of sleep of a high school student from the median. The average deviation of the amount of sleep of a high school student from the mean. The average amount of sleep high school students get. Average deviation of the amount of sleep of high school students from each other. D. Suppose a mistake was made when entering data. The 5th data value was erroneously recorded as 65 instead of 6.5. Recompute the range and standard deviation for the new data by changing the 5th data value to 65. New range = New Standard devation = Round to 2 decimal places. E. Based on your answers, is range a resistant statistic? Is standard deviation a resistant statistics? Remember that "resistance" means that the statistic does not substantially change in the presence of extreme observations. Range is a resistant statistic, but standard deviation is not. Both range and standard deviation are resistant statistics. Neither range nor standard deviation are resistant statistics. Standard deviation is a resistant statistic, but range is not.
