The daily high temperature in Winnipeg during the month of January is known to followa normal distribution with a mean of20C. It is also known that 95% of all daily hightemperatures in Winnipeg during the month of January are between32C and8C. What is the approximate value of?

(A) 3C(B) 4C(C) 6C(D) 8C(E) 12C

Option C) 6C

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 20C

Empirical Formula:

Thus, we can write:

Putting the value in the equation, we get,

Thus, the approximate value for standard deviation is

Option C) 6C
