1 answer:
A] The histogram of the data set given is shown on the attachment.
(<span>25,35,200,280,80,80,90,40,45,50,50,60,90,100,120,40,45,60,70,350</span>)
Measures of the center are:
25,75,125,175,225, 275, 325
The histogram is J-shaped
b] The measures of centers can on be obtained through Histogram, this is because they are not random numbers, they have to be generated from the histogram.

Answer:
a) $40920
b) $38500
Step-by-step explanation:
Given:
5 employees,
Mean = $40300
Median = $38500
Min = $32000
If he lowest paid employee gets a $3100 raise, then his salary becomes
$32000+$3100=$35100
a) If the mean was $40300, then the sum of 5 salaries is
After raising the lowest salary the sum becomes
and new mean is
b) The lowest salary becomes $35100. It is still smaller than the median, so the new median is the same as the old one.
New median = $38500
