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, record keeping, appearance, and
bedside manner with patients. Then an average is determined by
giving a weight of 2 for promptness, 4 for record keeping, 1 for
appearance, and 3 for bedside manner with patients. What is the
average rating for a nurse with ratings of 3 for promptness, 7 for
record keeping, 1 for appearance, and 5 for bedside manner? (Enter
your answer to one decimal place.)
Promptness | Record keeping | Appearance | Bedside manner | Total | ||
Wt | 2 | 4 | 1 | 3 | 10 | |
Nurse rate | 3 | 7 | 1 | 5 | ||
Wted record | 6 | 28 | 1 | 15 | 50 | |
Weighted mean = x1w1+x2w2+…+xnwn/w1+w2+..+wn = 50/10 = 5 |
