Question 15 Match each description to one of the z-scores: A. Z:+1.30; B. Z:1.55, C. Z: +1.00, D. Z: -2.20, E. Z: -0.90, F. 2: -0.14 1.Az-score that would be considered unusually far from the mean (there could be more than one correct answer, but just choose one) 2.Az-score that would be considered very close to the mean (there could be more than one correct answer, but just choose one) 3.AZ-score that is at the typical distance from the mean Question 16 Two different methods to measure sleep quality: Method A has to mean = 30 and SD = 10. Measure B has mean = 10 and SD = 2. Using Measure, A, person 1 is 8 points above average and gets a z-score of .80 Using Measure B, person 2 is 3 points above average and gets a z-score of 1.5 In relative terms, who has a higher score, person 1 or person 2? Explain in a sentence. Question 17 Suppose three different people have three different 2- scores. Match the z-score to the description for these three examples: A. Highest overall score, B. Closest to the mean, C. further from the mean Person 1:2 = -0.40 Person 2:2 =-1.50 Person 3:2 = +1.00
