z=2.27

Step-by-step explanation:

$z=\frac{x-\mu}{\sigma}$

where z is the deviation from mean.

mean (μ) = 35 inches

standard deviation (σ) = 11 inches

last year snow fall (x) = 60 inches

$z=\frac{x-\mu}{\sigma}$

$z=\frac{60-35}{11}$

z=2.27

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