Use the Empirical Rule to find the following probabilities. It is suggested that you draw a normal curve, label the r-values for 1, 2, and 3 standard deviations from the mean, and write in the probabilities between each standard deviation before attempting to answer the questions. The average life-span of a True Test auto battery is 39 months with a standard deviation of 3 months. Assume a normal distribution.

![Use the Empirical Rule to find the following probabilities. It is suggested that
you draw a normal curve, label the r-values for 1, 2, and 3 standard deviations
from the mean, and write in the probabilities between each standard deviation
before attempting to answer the questions.
The average life-span of a True Test auto battery is 39 months with a standard
deviation of 3 months. Assume a normal distribution.
1. We can expect 95% of the batteries to last between
33
and
45
months.
2. We can expect
15
% of the batteries to last less than 30
months.
3. We can expect 16
% of the batteries to last longer than 42
months.
4. We can expect
% of the batteries to last between 30 and
39 months.
5. We can expect
% of the batteries to last between 42 and
48 months.
