Asked Sep 12, 2019

At General Hospital, nurses are given performance evaluations to determine eligibility for merit pay raises. The supervisor rates the nurses on a scale of 1 to 10(10 being the highest rating) for several activities: promptness, recorded keeping, appearance, and bedside manner with patients. Then an average is determined by giving a weight of 2 for promptness, 3 for record keeping, 1 for appearance, and 4 for bedside manner with patients. What is the average rating for a nurse with ratings of 9 for promptness, 7 for record keeping, 6 for appearance, and 10 for bedside manner?

Step 1

To find average rating for a nurse, find the weighted average.

The formula for finding the weighted average is ∑*x _{i}w_{i}*/∑

Here, *x* represents several activities and *w* represents weight assigned to that activities.

Step 2

From the given data, the values of *x* (scores) are 9, 7, 6 and 10, and the values of weights (...
