Question

Over the past year, the vice president for human resources at a large medical center has run a series of three-month workshops aimed at increasing worker motivation and performance.

She collected the employee performance ratings recorded before and after workshop attendance and stored the paired ratings on sheet Ratings.

Compute descriptive statistics and perform a paired ttest.

State your findings and conclusions in a report to the vice president for human resources.
