Question

Exhibit 3-3Suppose annual salaries for sales associates from Hayley's Heirlooms have a bell-shaped distribution with a mean of $32,500 and a standard deviation of $2,500.The z-score for a sales associate from this store who earns $37,500 is ____

Answer 1

The z-score for a sales associate from this store who earns $37,500 is 2

Explanation:

From the given information:

mean
`\mu` = 32500

standard deviation = 2500

Sample mean X = 37500

From the given information;

The value for z can be computed as :

`z= (X- \mu)/(\sigma)`

`z= (37500- 32500)/(2500)`

`z= (5000)/(2500)`

z = 2

The z-score for a sales associate from this store who earns $37,500 is 2
