One year Josh had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of 2.94. Also, Sally had the lowest ERA of any female pitcher at the school with an ERA of 2.72. For the males, the mean ERA was 4.257 and the standard deviation was 0.664. For the females, the mean ERA was 4.848 and the standard deviation was 0.791. Find their respective z-scores. Which player had the better year relative to their peers, Josh or Sally? (Note: In general, the lower the ERA, the better the pitcher.) Josh had an ERA with a z-score of Sally had an ERA with a z-score of (Round to two decimal places as needed.)

A test was designed to have a mean of 80 and a standard deviation of 10. A random sample of 20 students at your school take the test, and the mean score turns out to be 85. Does this score differ significantly from 80? To answer this problem, you may want to use the Normal Distribution Calculator.
Use z scores to compare the given values. The tallest living man at one time had a height of 225 cm. The shortest living man at that time had a height of 104.3 cm. Heights of men at that time had a mean of 173.55 cm and a standard deviation of 5.15 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= and the z score for the shortest man is z= the V man had the height that was more extreme. (Round to two decimal places.)
