The difference between mean with outlier and mean without outlier is 0.93

Step-by-step explanation:

Total months are 12

So,

n=12

Sum of all values = 493.78

The mean is given by:

[tex]Mean=\frac{Sum\ of\ values}{No.\ of\ values}\\=\frac{493.78}{12}\\=41.148\ minutes[/tex]

The mean with outlier is: 41.148

Now to calculate the mean without outlier

We will subtract the outlier value from total sum

The outlier is 51.32 so the new sum will be: 493.78-51.32 =442.46

Total number of values = 12-1 = 11

The mean without outlier will be:

[tex]Mean\ without\ outlier=\frac{442.46}{11} =40.223[/tex]

Now the difference between both means is:

[tex]41.148-40.223=0.925 => 0.93[/tex]

The difference between mean with outlier and mean without outlier is 0.93
