The answer is below

Step-by-step explanation:

The number of vacation days taken by employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? More than 21 days?

Z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. It is given by the equation:

Given that: μ = 14, σ = 3

a) For x < 10

From the normal distribution table, P(x < 10) = P(z < -1.33) = 0.0918

b) For x > 21

From the normal distribution table, P(x > 21) = P(z > 2.33) = 1- P(z < 2.33) = 1 - 0.9901 = 0.0099
