1. construct the frequency distribution table and fine the mean absolute deviation of the following data: 5 34 12 32 17 19 34 17 4 32 30 12 11 7 9 10 15 16 17 15 18 22 26 23 25 27 28 29 13 15 14 30 20 23 22 21 23 13 2. a statistics professor reported that the mean score in a recent quiz is 72 and the standard deviation is 6. a. What is the proportion of students who obtained scores between 50 and 75? b. If a score is equivalent to z = -1.25, what is the raw score? c. How many students obtained higher than 80? 3. calculate the coefficient of variation. Mean Standard deviation 15 3 Age (in years) of students Weight in pounds 80 12
