Mr. Howard, the manager of a grocery store, gets a complaint from a customer: “Mr. Howard, when I check out I want the fastest register. Too often I am in a line where there is some sort of problem and I have to wait and wait and wait … I think I am going to stop coming here!” You suggest to Mr. Howard that he tries a different strategy from his current one where a customer chooses from multiple registers (STRATEGY 2). You suggest that he sets up the store so that the customer will enter one single line and then break off at the end to the next available cash register (STRATEGY 1). Below are a sample of waiting times (in minutes) that you collected for the two methods. You have agreed to help Mr. Howard analyze the data. STRATEGY 1 (SL): Single line/multiple registers (new strategy): 6.5, 6.6, 6.7, 6.8, 7.1, 7.3, 7.4, 7.7, 7.7, 7.7 STRATEGY 2 (ML): Multiple lines/multiple registers (current strategy): 4.2, 5.4, 5.8, 6.2, 6.7, 7.7, 7.7, 8.5, 9.3, 10.0 a) For each strategy, find the 5-number summary and construct box-plots. Compare the distribution for each strategy using several sentences. B) Compute the sample mean, median and mode for each strategy. Using these values, which strategy appears to be more effective? Explain using several complete sentences. C) Compute the range and sample standard deviation (two decimal places) for each strategy. Using these values, which strategy appears to be more effective? Explain using several complete sentences. D) Using your results, which strategy would you recommend to Mr. Howard? Explain using several complete sentences.

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
