Difference between the mean of the data, including the outlier and excluding the outlier is;

B: 0.93

<h3>Mean average</h3>

Her time in minutes for the given months are;

  • January = 41.55 minutes
  • July = 36. 38 minutes
  • Feb = 42.51 minutes
  • Aug = 38.48 minutes
  • Mar = 43. 01 minutes
  • Sept = 41.87 minutes
  • Apr = 39. 76 minutes
  • Oct = 51.32 minutes
  • May = 37. 32 minutes
  • Nov = 42.59 minutes
  • June = 35.28 minutes
  • Dec = 43.71 minutes

Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32

Total number of minutes with outlier = 493.78 minutes

Number of months = 12

Thus;

Mean with outlier = 493.78/12

Mean with outlier = 41.15 minutes

Mean without outlier = (493.78 - 51.32)/(12 - 1)

Mean without outlier = 40.22 minutes

Thus;

Difference in both means = 41.15 - 40.22

Difference = 0.93
