The following table shows the number of complaints received each day by a customer service department over the past 20 days.
The numbers are shown below:
8, 10, 8, 2, 4, 13, 23, 10, 6, 3, 18, 16, 11, 3, 3, 17, 12, 8, 10, 6
How would I describe the shape of the distribution? For example does the shape shift to the left or right?
What does it mean to compute the percentage of data lying within one, two, three, and four standard deviations of the mean?
