Answer:

$z =\frac{50-64}{7}= -2$

$z =\frac{43-64}{7}= -3$

We know that within two deviations from the mean we have 95% of the data from the empirical rule so then below 2 deviation from the mean we have (100-95)/2 % =2.5%. And within 3 deviations from the mean we have 99.7% of the data so then below 3 deviations from the mean we have (100-99.7)/2% =0.15%

And then the final answer for this case would be:

$2.5 -0.15 = 2.35\%$

Step-by-step explanation:

For this case we have the following parameters from the variable number of motnhs in service for the fleet of cars

$\mu = 64, \sigma =7$

For this case we want to find the percentage of values between :

$P(43< X< 50)$

And we can use the z score formula given by:

$z = \frac{X-\mu}{\sigma}$

In order to calculate how many deviation we are within from the mean. Using this formula for the limits we got:

$z =\frac{50-64}{7}= -2$

$z =\frac{43-64}{7}= -3$

We know that within two deviations from the mean we have 95% of the data from the empirical rule so then below 2 deviation from the mean we have (100-95)/2 % =2.5%. And within 3 deviations from the mean we have 99.7% of the data so then below 3 deviations from the mean we have (100-99.7)/2% =0.15%

And then the final answer for this case would be:

$2.5 -0.15 = 2.35\%$
