Problem 1a. What is the probability that a person selected at random from this HWAS data set will be between 30 and 39 years of age inclusive?
b. What is the probability that a person selected at random from this HWAS data set will be shorter than 65" or taller than 70"? Problem 2 a. Using Ideal Weight data, make a histogram, get Mean, Std.Deviation, and Five-Number Summary. Describe the distribution. Description should include min, max, center, spread, number of peaks, shape, identification of outliers (chap.3-4) b. Calculate the z-score for the weight 170 lbs. What is the probability P of weighing more than 170 -- P(x>170) ? (hint: see chap.6-2 The Standard Normal Distribution)
