Question

Weekly wages at a certain factory are

normally distributed with a mean of
$400 and a standard deviation of $50.
Find the probability that a worker
selected at random makes between
$300 and $350.

Answer 1

0.136

Explanation:

If you have a calculator with statistical functions, this problem is straightforward.

Use the normcdf function as follows:

normcdf(300,350,400,50) = 0.136

This result is the probability that a worker makes between $300 and $350 per week: 0.136
