Describe shape-center and spread of data after omit outlier
(a) Why is the number of doctors per 100,000 people a better measure of the availability of health care than a simple count of the number of doctors in a state? (b) Make a graph to display the distribution of doctors per 100,000 people. Write a brief description of the distribution. Are there any outliers? If so, can you explain them? 1.20 Here are the monthly percent returns on Philip Morris stock for the period from July 1990 to May 1997. (The return on an investment consists of the change in its price plus any cash payments made, given here as a percent of its price at the start of each month.) (a) Make either a histogram or a stemplot of these data. How did you decide which graph to make? (b) There is one clear outlier. What is the value of this observation? (It is explained by news of action against smoking, which depressed this tobacco company stock.) Describe the shape, center, and spread of the data after you omit the outlier. (c) The data appear in time order readi.
