<span>Assuming a normal distribution the noise level is below 44dB 90% of the time.
Looking up the standard deviation that goes along with .01 on a normal distribution chart, we find that 2.33 standard deviations is the answer. Given the standard deviation of six we turn this in to deviation in decibels from the mean:
6*2.33 = 13.98
Add this to the mean to get
30+13.98=43.98
which we round to 44dB</span>

It means that per hour, the individual performance is $200
We simply divide the total sales by the number of shift hours, so that the sales per hour can determined
