1. A developmental psychologist was interested in how long it would take a particular 7- year-old child to complete three different aptitude tests as compared with 7-year-olds in the general population. The child's time for reading was 31 minutes (population: M- 29, SD = 4). For math, it was 26 minutes (population: M- 32, SD - 2). For science, it was 40 minutes (population: M= 31, SD = 4). a. Calculate the child's z- scores for each of the aptitude tests. (15 pts) b. What proportion of the normal distribution corresponds to z-score values greater than the child's z-score on the science test. (5 pts) c. Which aptitude test(s) took the child substantially more time to complete as compared with other 7-year-olds? (5 pts)
