Question

The annual snowfall in a town has a mean of 35 inches and a standard deviation of 11 inches. Last year there were 60 inches of snow. How many standard deviations from the mean is that

Answer 1

z=2.27

Explanation:

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

where z is the deviation from mean.

mean (μ) = 35 inches

standard deviation (σ) = 11 inches

last year snow fall (x) = 60 inches

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

`z=(60-35)/(11)`

z=2.27

now, the standard deviation for the 60 inches snow from the mean is calculated to be 2.27
