The same question but the last 2, I have calculated the same way as the 1st year and I keep getting it incorrect.

Malameter Manufacturing provides on-site repairs for its fabrications. Management would like to perform a cost analysis of these repairs. Because outliers are relatively rare, management is okay with seeing a basic analysis. Below is cost information from last year.
