Coefficient of Variation Calculation

A data analyst compiled the following set of numbers representing the daily sales (in thousands) of a small retail store over a two-week period:

12, 15, 14, 18, 20, 17, 16, 21, 19, 22, 23, 25, 24, 26, 30, 28

Using this dataset, what is the coefficient of variation (CV) for the daily sales? The coefficient of variation is defined as the ratio of the standard deviation to the mean, expressed as a percentage. Calculate the mean and standard deviation accurately to determine the CV.
