Step 1

a)

About 68% of the observations between the value 1 is ** 364** and the value 2 is

The mean of the normal distribution is 380 and the standard deviation is 16.

**Empirical Rule:**

- The percentage of values lies between one standard deviation from the mean is 68%.
- The percentage of values lies between two standard deviation from the mean is 95%.
- The percentage of values lies between one standard deviation from the mean is 99.7%

Step 2
