What is the correct interpretation of Jackson’s z-score? How many pairs of shoes does a typical teenage boy own? To find out, two AP® Statistics students surveyed a randomsample of 20 male students from their large high school. Then they recorded the number of pairs of shoes that each boyowned. Given is a dotplot of the data. Jackson, who reported owning 22 pairs of shoes, has a standardized score of z =1.10.What is the correct interpretation of Jackson's z-score?510152025303540Number of pairs of shoesO His value is 1.10 standard deviations above the mean.O Jackson owns 1.10 more pairs of shoes than average.O The number of pairs of shoes owned by Jackson is1.10 standard deviations above the mean number ofpairs of shoes owned by the boys in the sample.O To calculate this value, take Jackson's number of pairsof shoes, subtract the class average, and then divide bythe standard deviation.O Jackson's pairs of shoes outnumbered his classmatesby a factor of 1.10.prt scGH

A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean mnonthly mileage, u, of cars rented in the U.S. this year. The consumer group has good reason to believe that the mean monthly mileage of cars rented in the U.S. this year is greater than last year's mean, which was 2750 miles. The group plans to do a statistical test regarding the value of u. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2900 miles and the standard deviation to be 700 miles. Based on this information, complete the parts below.
