The student will calculate probabilities using the Central Limit Theorem.

Given

Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she has found that the reviews take her approximately 4 hours each to do with a population standard deviation of 1.2 hours. Let
$X$ be the random variable representing the time it takes her to complete one review. Assume
$X$ is normally distributed. Let
$\overline{X}$ be the random variable representing the mean time to complete the 16 reviews. Let
$\mathrm{\Sigma X}$ be the total time it takes Yoonie to complete all of the month’s reviews. Assume that the 16 reviews represent a random set of reviews.

Distribution

Complete the distributions.

$X$ ~

$\overline{X}$ ~

$\mathrm{\Sigma X}$ ~

Graphing probability

For each problem below:

Sketch the graph. Label and scale the horizontal axis. Shade the region corresponding to the probability.

Calculate the value.

Find the probability that
one review will take Yoonie from 3.5 to 4.25 hours.
