Question
Lower than this one. In 2010, the total MCAT scores were close to Normal with mean 25.0 and standard deviation 6.4. William scored 32. What was his percentile? Perfect SAT scores. It is possible to score higher than 1600 on the combined Mathematics and Reading portions of the SAT, but scores of 1600 and above are reported as 1600. The distribution of SAT scores (combining Mathematics and Reading) was close to Normal with mean 1021 and standard deviation 211. What proportion of SAT scores for these two parts were reported as 1600? Heights of women. The heights of women aged 20 to 29 follow approximately the N(64.3, 2.7) distribution. Men the same age have heights distributed as N(69.9, 3.1). What percent of young women are taller than the mean height of young men? Weights aren't Normal. The heights of people of the same sex and similar ages follow a Normal distributed. The weights of women aged 20 to 29 have mean 155.9 pounds and median 144..0 pounds. The first and third quartiles are 124.1 pounds and 173.7 pounds. What can you say about the shape of the weight distribution? Why?Explanation / Answer
3.41) F(64.3,2.7)
M(69.9,3.1)
AS STD DEVIATION OF FEMALES IS 2.7
RANGE WILL BE OF HEIGHT = (61.6,67)
RANGE OF MALE HEIGHT = (66.8,73)
WE HAVE TO FIND THE PERCENTAGE OF WOMEN ABOVE THE MEAN HEIGHT OF MEN.
IF WE GO BY THE RANGE OF WOMEN HEIGHT THE HIGHEST IS 67 WHILE THE MEN MEAN HEIGHT IS 69.9
SO IT IS NOT POSSIBLE FOR WOMEN TO BE OF MORE HEIGHT THEN MEN
