15. Alexander, a meteorologist, is studying the daily high temperatures over the past 50 years during the month of July for the cities of Chicago and Phoenix (a sample size of 1550 July days for each city). Alexander found that in Chicago, the middle 95% of July days have a high temperature between 70° F and 98° F, while in Phoenix, the middle 95% of July days have a high temperature between 94° F and 110° F. On one particular July day, the temperature in Phoenix is exactly 17° F higher than the temperature in Chicago. Which of the following is not a valid pair of z-scores for the two cities? Circle your answer. Chicago: z = 1.7143 Phoenix: z= -3.2500 Chicago: z = 0.4286 Phoenix: z = 0.7500 Chicago: z = 0.8571 Phoenix: z=-1.2500 Chicago: z= 1.5714 Phoenix: z = 2.5000 15.
