Label the normal curve with the scores (and include z–scores). Answer the following: a) What percent of scores are less than 38? b) What percent of scores are between 42 and 44? c) What percent of scores are higher than 46? total:
Recall: 68% 95% 99. 7% For a normal distribution, 1 68 % of the data falls within ____ σ of 2 σ of 95 % of the data falls within ____ 3 σ of 99. 7 % of the data falls within ____
2) On a recent quiz, the average score was 40 and the standard deviation was 2. Label the normal curve with the scores (and include z–scores). Answer the following: a) What percent of scores are less than 38? +1 50% – 34% = 16% +2 b) What percent of scores are between 42 and 44? 47. 5% – 34% = 13. 5% total: c) What percent of scores are higher than 46? +2 50% – 49. 85% = 0. 15% +1 +2 47. 5% +1 49. 85% 34 – 3 36 38 – 2 – 1 +1 labeled scores 34% 40 0 42 44 1 2 +1 labeled z–scores 46 3 z–score

Label the normal curve with the scores (and include z–scores). Answer the following: a) What percent of scores are less than 38? b) What percent of scores are between 42 and 44? c) What percent of scores are higher than 46?
1) Compute the standard deviation of the data set {6, 3, 4, 4, 8}. 4 3 2 (6 – 5)2 = (1)2 = 1 (3 – 5)2 = (– 2)2 = 4 (4 – 5)2 = (– 1)2 = 1 (8 – 5)2 = (3)2 = 9 1 6 5
