Answer:
a) Mean = 161.666667
b)Mode = 140
c) Median =160
d) Range =130
Step-by-step explanation:
Given that the weekly salaries of six employees =$140, $220, $90, $180, $140, $200
Mean =Total number of salaries/ Number of salaries
=$140 +$220 +$90 +$180 + $140 +$200 /6=970/6= 161.666667
Mode = The number with the highest frequency ie the number that occurs most in the listed salaries
$140, $220, $90, $180, $140, $200
Therefore 140 is the mode
Median = The number that occurs in the middle, Now that we have a list of even Numbers, our median would be the sum of the two middle numbers divided by 2 after arranging in ascending order fro least to greatest
$90, $140,$140, $180, $200,$220
Median =$140+ $180 / 2 = 160
Range = The difference between the highest and lowest number in the sample
$220-$90=130
