NBA Draft Picks. FromWikipedia’s on-line document “List of First Overall NBA Draft Picks,” we found that, since 1947, 10.4% of the number-one draft picks in the National Basketball Association have been other than U.S. nationals. a. Identify the population. b. Identify the specified attribute. c. Is the proportion 0.104 (10.4%) a population proportion or a sample proportion? Explain your answer.
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 37% with a margin of error of 2.5%. Describe the conclusion about p using an absolute value inequality. . That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to ≤ . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to ≥. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).
