Answer appropriately.

Which of the following statements best explains the relationship between Quadratic Discriminant Analysis and naive Bayes with Gaussian distributions in each class A) Quadratic Discriminant Analysis is a more flexible class of models than naive Bayes B) Quadratic Discriminant Analysis is a less flexible class of models than naive Bayes C) Quadratic Discriminant Analysis is an equivalently flexible class of models to naive Bayes D) For some problems Quadratic Discriminant Analysis is more flexible than naive Bayes, for others the opposite is true

2. Suppose 42%% of Ph.D.s in statistics/biostatistics are earned by women and a random sample 36 statistics/biostatistics Ph.Dis is obtained. (You may want to use technology to compute some of the probabilities.) a. What's the probability none of the 36 statistics/biostatistics Ph.D.s are women? b. What's the probability at least 1 of the 36 statistics/biostatistics Ph.D.s is a woman? c. How many women do you expect in the sample of the 35 statistics/biostatistics Ph.D.s? d. What's the probability fewer than half of the 36 statistics/biostatistics Ph.D.s are women?CHAPTER 6 Continuous Probability Distributions CONTENTS 6.3 NORMAL APPROXIMATION STATISTICS IN PRACTICE: OF BINOMIAL PROCTER & GAMBLE PROBABILITIES 61 UNIFORM PROBABILITY 6.4 EXPONENTIAL DISTRIBUTION PROBABILITY Area as a Measure of Probability DISTRIBUTION Computing Probabilities for the 62 NORMAL PROBABILITY Exponential Distribution DISTRIBUTION Relationship Between the Normal Curve Poisson and Exponential Standard Normal Probability Distributions Distribution Computing Probabilities for Any Normal Probability Distribution Grear Tire Company Problem2.
