Maggie attends Happy Days preschool. The preschool assessed the children’s motor skills (i.e. the ability to tie their shoes), social skills (i.e. sharing and saying please) and school readiness (i.e. knowledge of ABC’s & basic counting ability). The motor skills test has a class mean of 6.00 with a standard deviation of 1.00. The social skills test has a class mean of 10.00 with a standard deviation of 2.00. The school readiness test has a class mean of 16.00 with a standard deviation of 4.00. For each test higher score means better performance of that skill. Maggie’s parents are given a report card that indicate Maggie’s Z scores on each test which are motor skills = -0.32, social skills = 1.50 & school readiness = 0.00.

The principal of a school wants to identify the students who are in the top 5% of the class for participation in accelerated work in reading. What is the minimum raw score a student must have to be in the top 5% a. 65 b. 78.5 c. 66.65 d. 77.58
Raw scores on behavioral tests are often transformed for easier comparison. A test of reading ability has mean 60 and standard deviation 10 when given to third graders. Sixth graders have mean score 83 and standard deviation 9 on the same test. To provide separate "norms" for each grade, we want scores in each grade to have mean 100 and standard deviation 20. (Round your answers to two decimal places.) (a) What linear transformation will change third-grade scores x into new...
