SOLUTION: An angle has mean of 19° and standard deviation of 8°. If a value from this distribution is chosen at random, what is the probability that it will be between 19° and 24°?
Hi
mean of 19° and standard deviation of 8°
probability that it will be between 19° and 24° |24° is 3SD from mean
P(0 < z < 3) = P( z < 3) - P (z<0) = .9987 - .50 = .4987
