ANT371H1 Study Guide - Histogram, Standard Deviation, Random Variable
Document Summary
__________ (5) [4 pts] consider a random variable x ~ n(60,10) (which means that x is normally distributed with mean 60 and variance 10). For which of the following would the probability be larger than p(x>90)? (a) p(q>90) where q ~ n(62,10) (b) p(w>90) where w ~ n(60,12) (c) p(y>90) where y ~ n(62,12) (d) all of the above. __________ (6) [4 pts] suppose you collected data on 10,000 people. For a variable (w) you calculate a mean of 0. 496 and a standard deviation of 0. 506. You also construct a histogram, which is shown here.
