A normal distribution has a mean = 25 and a standard deviation σ = 5. Find the probability that a randomly selected x-value from the distribution is between 15 and 35. Write your answer as a decimal.
-----
z(15) = (15-25)/5 = -2
z(35) = (35-25)/5 = 2
-------
P (15 < x < 35) = P(-2 < x < 2) = normalcdf(-2,2) = 0.9545
