We collected 50 pennies and recorded their ages, by calculating

AGE = CURRENT YEAR = YEAR ON PENNY.

5 1 9 1 2 20 0 25 0 17

1 4 4 3 0 25 3 3 8 28

5 21 19 9 0 5 0 2 1 0

0 1 19 0 2 0 20 16 22 10

19 36 23 0 1 17 6 0 5 0

a. Before drawing any graphs, try to visualize what the distribution of penny ages will look like. Will it be mound-shaped, symmetric, skewed right, or skewed left?

b. Draw a relative frequency histogram to describe the distribution of penny ages. How would you describe the shape of the distribution?

Step 1

a.

The distribution of penny ages will look like a skewed right distribution because from the given ages it can be observed that there are more pennies with lesser ages when compared to the pennies with higher ages. Therefore, the distribution will be peaked towards the left which will be having lower ages like 0, 1, 2 and so on and the peak will be gradually decreased when the age of the pennies increase.

Hence, the distribution of ages of pennies is skewed right.

Step 2

b.

The relative frequency distribution of the ages of pennies is given below:

Step 3

Using the above relative frequency distribution, the histogram f...
