5. | Basic Computation: Class Limits A data set with whole numbers has a low value of 20 and a high value of 82. Find the class width and class limits for a frequency table with 7 classes. 6. | Basic Computation: Class Limits A data set with whole numbers has a low value of 10 and a high value of 120. Find the class width and class limits for a frequency table with 5 classes. 7. Interpretation You are manager of a specialty coffee shop and collect data throughout a full day regarding waiting time for customers from the time they enter the shop until the time they pick up their order. (a) What type of distribution do you think would be most desirable for the wait- ing times: skewed right, skewed left, mound-shaped symmetric? Explain. (b) What if the distribution for waiting times were bimodal? What might be some explanations?
