Question
Chapter 3.1, Problem 3.2E
(a)
To determine
To explain the 80th percentile of his all races and the 50th percentile in the league.
(a)
Expert Solution
Explanation of Solution
A percentile defines that a certain percent of data falls less than that now the 80th percentile of all his races so far means that his performance is better than 80% of the previous his performance, while the 50th percentile in league means that the runner is better than the 50% of the other racers.
(b)
To determine
To explain the 50th percentile all her swim meet and 80th percentile in league swim meet.
(b)
Expert Solution
Explanation of Solution
The 50th percentile of all her swim meet means that the performance of her is better than her 50% of the earlier swim meet and the 80th percentile in league swim meet means that her performance in league is better than 80% of the other swimmers.

Wing Foot knows that its stores will not show a profit unless they gross over $940,000 per year. Let A be the event that a new Wing Foot store grosses over $940,000 its first year. Let B be the event that a store grosses over $940,000 its second year. Wing Foot has an administrative policy of closing a new store if it does not show a profit in either of the first two years. Assume that the accounting office at Wing Foot provided the following information: 58% of all Wing Foot stores show a profit the first year; 72% of all Wing Foot store show a profit the second year (this includes stores that did not show a profit the first year); however, 86% of Wing Foot stores that showed a profit the first year also showed a profit the second year. Compute P(B|Ac). Round your answer to the nearest hundredth.arrow_forward
