The attached Excel spreadsheet includes 500 randomly collected data points describing how many minutes of physical exercise different people get each day, according to an accelerometer.

a) Make a histogram in Excel of the randomly collected data points using the following bins:

0-10, 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-80

b) Describe this histogram's center, spread, and shape.

c) Select 10 groups of 50 random data points each. It is OK if you have overlapping data points. List these groups.

d) Take the mean of each group and make a histogram of these 10 data points using the same bins from part a)

e) Describe the histogram's center, spread, and shape.

f) Explain how these two diagrams represent the Central Limit Theorem.
