Question - Optimizing Mean Calculation by Removing Two Highest Values
Solution:
The question asks us to determine which two values should be removed from the data set in order to achieve the lowest total mean. To find this out, we should look for the two highest values, because removing them will reduce the overall total the most, and hence lower the mean.From the image, the two highest values in the table are 99 (for Product #4 in Week 6) and 91 (for Product #1 in Week 4).To summarize: Removing the two largest values, which are 99 and 91, will result in the lowest total mean. So the correct answer would be option B: 91 and 99.
