Question

A large company claims that the average age of their employees is 32 years, with a standard deviation of 4 years. The average age of employees in the sales department at the company is 27 years. Given that the data is approximately normal, find the probability that an employee, chosen at random, will be younger than 27 years. A portion of the standard normal table is provided.

Answer 1

Answer:

10.56%

Step-by-step explanation:

Average age of employees  = 32

Standard Deviation = 4

Z score =  (Value -  Average)/Standard deviation

=> Z score =  (27 - 32)/4

=> Z score = -5/4

=> Z score = -1.25

Z score = -1.25  is 10.56 %

=> 10.56% employee are below 27 years

Probability that employee chosen is younger than 27  =  10.56%
