I think I solved it, but the rounding is causing me problems? I included my work at the end. Please let me know what I am doing wrong.
I tried 0.097, 0.098, 10.000 and none of these were the answer.
Each day, a FedEx competitor processes approximately 75,000 shipments. Suppose that they use the same Service Quality Index as FedEx and identified the following numbers of errors during a 5-day week (see the "FedEx: Measuring Service Performance" box). These values are hypothetical and do not reflect any real companys actual performance.
Description | Weight | Number of Errors |
Complaints reopened | 3 | 110 |
Damaged packages | 10 | 18 |
International | 1 | 108 |
Invoice adjustments | 1 | 283 |
Late pickup stops | 3 | 206 |
Lost packages | 10 | 4 |
Missed proof of delivery | 1 | 22 |
Right date late | 1 | 755 |
Traces | 3 | 118 |
Wrong day late | 5 | 20 |
Compute the Service Quality Indicator by finding the weighted sum of errors as a percentage of total shipments. Do not round intermediate calculations. Round your answer to three decimal places.
Service Quality Indicator (SQI): 0.0979 rounded to 0.098 ( is my answer) my work is below
