Describe the shape, mean, and standard deviation of the distribution of ride cost in cents b) Knoebels' managers decide to increase the cost of each ride by 25 cents. How would this the shape, center, and variability of this distribution compare with the distribution of cost in Question 17 c) Now suppose you convert the increased costs from Question b to z-scores. What would be the shape, mean, and standard deviation of this distribution? ........ ***
