The number of rubber bands in a 1/4 pound bag has a mean of 180 rubber bands in a standard deviation of nine rubber bands Mary’s bags has 198 rubber bands. What is the difference between Mary’s bag total and the mean



Answer :

To solve this problem, we need to find the difference between Mary's bag total and the mean of the number of rubber bands in a 1/4 pound bag.

Given information:
- The mean of the number of rubber bands in a 1/4 pound bag is 180.
- The standard deviation of the number of rubber bands in a 1/4 pound bag is 9.
- Mary's bag has 198 rubber bands.

Step 1: Find the difference between Mary's bag total and the mean.
Difference = Mary's bag total - Mean
Difference = 198 - 180 = 18

Therefore, the difference between Mary's bag total and the mean is 18 rubber bands.
