Question

What is sigma(x -3)^3 for the following scores? 6, 0, -3, 4 55 -5 25 58 A very difficult exam will produce a frequency distribution of scores that is symmetrical negatively showed positively skewed bell shaped Consider the following distribution of scores for 3 through of scores that is The 50^th percentile 4.5 d. 11 3 4. 3.5 4.0 4.5 112 The range 101 1 to 113 112 113 The mean the mode 113 3.75 4.0 4.25 The median"- 113 3.75 4.0 4.25 mu 43.0 17.00 17.75 5.75 A distribution has mu = 6 and sigma = 2. If you multiply each score with 30, 2 30.10 10.30 11, 7 Which set of scores has the least amount of variability? 11, 17, 31, 53 5, 11, 42, 22 27, 105, 10, 80 145, 143, 145, 147.
