Answer to Question 1

The mean is the average value of a set of observations. It is calculated as the sum of all the different items divided by the number of items.
The average value is the sum of all popsicles sold divided by the number of people who bought them. If each of the 5,000 people bought an average of 2 popsicles, that means that 10,000 popsicles were sold that day.
