According to the data, the mean quantitative score on a standardized test for female college-bound high school seniors was 500. The scores are approximately Normally distributed with a population standard deviation of 100. What percentage of the female college-bound high school seniors had scores above 637? Answer this question by completing parts (a) through (g) below.
e. Use the Normal table to find the area to the left of the z-score that was obtained from a standardized test score of 637. The area to the left of the z-score is
Homework Answers
e) Z = (X - mean) / sd = (637 - 500) / 100 = 1.37
P(X < 637) = P(Z < 1.37) = 0.9147 (ans)

A standardized visual working memory test has a population mean of 60 and a standard deviation of 6. Because the scores are normally distributed, the whole distribution of scores can be converted into a Z distribution. Each raw score in the original distribution has a corresponding Z score in the Z distribution. The Z distribution has a symmetrical bell shape with known properties, so it's possible to mathematically figure out the percentage of scores within any specified area in the...
