1. Calculate relative frequencies for; Overall Type of Calls, CallQuality and Call Errors.
2. Calculate the following probabilities:
   • CLM Error and AM Shift
   • COV Error and PM Shift
   • SAV Error or AM Shift
   • Given that the call comes in the morning, what is theprobability of a CLM Error
3. NARRATIVE: Based upon the probabilities in step 2, whicherror(s) should the company focus on for improvement? Should theydirect their attention to a particular shift?
4. If a sample size of 15 is used and we assume calls are eithercorrect we can model the call quality using a binomialdistribution. Based upon the probability of an error (provided inthe Quality Summary under Call Quality), predict the probabilityof:
   • Exactly 0 errors occurring in 15 calls
   • Less than 2 errors occurring in 15 calls
   • 5 or more errors occurring in 15 calls
5. Provide Descriptive Statistics for Call Time to include; Mean,Standard Deviation and the 5-number summary.
6. Using the Call Time Mean and Standard Deviation from theQuality Sample, find the probability of a call time less than 7minutes, between 7 and 9 minutes, and greater than 9 minutes.
7. NARRATIVE: From past research the company knows that customersexpect to have their calls handled without error and withinapproximately 7.5 minutes on the phone. Use the information fromsteps 4-6 to evaluate how well the company is meeting theseexpectations.
