• Exercise Problem 3.68::::: Call centers today play an important role in managing day-to-day business communications with customers. It’s important, therefore, to monitor a comprehensive set of metrics, which can help businesses understand the overall performance of a call center. One key metric for measuring overall call center performance is service level which is defined as the percentage of calls answered by a human agent within a specified number of seconds. The file Service Level contains the following data for time, in seconds, to answer 50 incoming calls to a financial services call center:
16 14 16 19 6 14 15 5 16 18 17 22 6 18 1015 12 6 19 16 16 15 13 25 9 17 12 10 5 1523 11 12 14 24 9 10 13 14 26 19 20 13 24 2815 21 8 16 12 Calculate the mean, median, range, and standard deviation for the speed of answer, which is the time to answer incoming calls.
List the five-number summary.
Construct a boxplot and describe its shape.
What can you conclude about call center performance if the service level target is set as “75% of calls answered in under 20 seconds?”
• Exercise Problem 3.70:::::: Data were collected on the typical cost of dining at American-cuisine restaurants within a 1-mile walking distance of a hotel located in a large city. The file Bundle contains the typical cost (a per transaction cost in \$) as well as a Bundle score, a measure of overall popularity and customer loyalty, for each of 40 selected restaurants.
Source: Data extracted from www.bundle.com via the link on-msn.com/MnlBxo.
For each variable, compute the mean, median, first quartile, and third quartile.
For each variable, compute the range, interquartile range, variance, standard deviation, and coefficient of variation.
For each variable, construct a boxplot. Are the data skewed? If so, how?
Calculate the coefficient of correlation between Bundle score and typical cost.
What conclusions can you reach concerning Bundle score and typical cost?
