Question 1050517: Assume the random variable x is normally distributed with mean u
equals 81 and standard deviation o equals 4 Find the indicated probability.
​P(68 less than x less than 79)​P(68less than x less than79​)equals nothing
​(Round to four decimal places as​ needed.)

You can put this solution on YOUR website!
u equals 81 and standard deviation o equals 4
P(68 ≤ x ≤ 79) = normalcdf(68,79,81,4) Use Your Calculator
In general TI syntax is normalcdf(smaller, larger, µ, σ).
One could also Use a Casio fx-115 ES plus 0r fx-991 ES plus
