Question

Last year, the personal best high jumps of track athletes in a nearby state were normally distributed with a mean of 221 cm & a standard deviationof 11 cm. What is the probability that a randomly selected high jumper has a personal best between 199 & 210 cm?

Answer 1

@sourwing do you know to do this?

Answer 2

use the Z score equestion
\[Z=\chi-\mu/ \sigma \sqrt{n}\]
do them separately, find both of the answer, look at the z-table and find the probability, then subtract the larger number from the smaller number.

Answer 3

n= 1 because it says if a randomly selected high jumper meaning one
