Analyzing Statistical Data about Pairs of Shoes
Problem Statement:

A teacher decides to survey 10 students at a middle school. He asks each student how many pairs of shoes he or she owns and records the number. The teacher then creates the above data table. Plot the data on the x-axis on the grid. What is the mean value of the data? What value would you expect if the teacher decided to ask one more student how many pairs of shoes he or she owned? Run the program to answer the questions.
