What is the probability that an elementary school student in southern Kenya is greater than or equal to 41.3 inches tall? (Round to the nearest percent.)

z score is (x - mean)/standard deviation

so (41.3 - 40.1)/2.2

What is the probability that an elementary school student in southern Kenya is greater than or equal to 41.3 inches tall? (Round to the nearest percent.)

z score is (x - mean)/standard deviation

so (41.3 - 40.1)/2.2

- and look up that on a standard normal distribution chart
- z-chart
- to that value for z (.55) is .7088
- that is the probability of LESS than z(.55)
