Answer 1

Median 665

Mean 795

b) 2 employees the ivnentory manager and the supervisor

c)

B. The median best describes the typical wage. The mean is not a good measure of center because it is affected by the two higher salaries.

Step-by-step explanation:

Wages:

450

500

830

1400

Median: the average of the two middle values

(500 + 830)/2 = 665

Mean: average of all the values

(450 + 500 + 830 + 1400) / 4 = 795

question c)

The mean uses the higher salaries while the median don't.

So D is incorrect.

Also, the median is not affected by the multitude of dplicate salaries as it will only take the two middle salaries and divide them. It will be the mean which does that.

So that discards A and C
