<h3>What is standard deviation?</h3>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value
Here given that
The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes
mean=μ=60
standard deviation=σ=15.9
number of sample=n=40

Now we can calculate z by z-score formula as

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19
