Question 923420: For the question "Last year, the personal best high jumps of track athletes in a nearby state were normally distributed with a mean of 221 cm and a standard deviation of 11 cm. What is the probability that a randomly selected high jumper has a personal best between 199 and 210 cm?" I found the solution P(199 < x < 210) = P(-2 < z < -1) = 0.1359. I understand how they got P(199

You can put this solution on YOUR website! mean of 221 cm and a standard deviation of 11 cm.
P(199 < x < 210) = P(-2 < z < -1) = normalcdf(-2,-1) = .1359
0r
P(-2 < z < -1) = P(z< -1) - P(z< -2) = .1587 - .0228 = .1359
