What is a stem-and-leaf plot?
The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:
4|5 = 45.
Considering the key in this problem, the measures(number of cups of coffee sold each day) are given as follows:
50, 52, 58, 59, 60, 63, 63, 65, 69, 69, 72, 75, 77, 78.
Hence:
a) The maximum number of cups of coffee sold on a single day is of 78.
b) In 5 days, less than 60 cups were sold.
The average of a data-set is given by the sum of all observations in the data-set divided by the number of observations, hence:
M = (50 + 52 + 58 + 59 + 60 + 63 + 63 + 65 + 69 + 69 + 72 + 75 + 77 + 78)/14 = 65.
The average sales is of 65 cups of coffee a day.
