Suppose you are developing a convenient-home-test-for-blood-alcohol·levels. It could be useful. for telling when someone is too inebriated to safely-drive home, but you aren't sure how. accurate the test is. By design, the test should be positive when blood alcohol·level-is-above. 0.05%. The test has been used·on·a·large·number·of·subjects where·a·more expensive,·less· convenient test is known to give perfectly accurate results. The table below.shows the. proportions for the outcome of the new test-and-true-blood-alcohol-status: TestResult Positive Negative BAC Over 0.05 0.12 0.03 BAC Under 0.05 0.21 0.64 1. What is the probability that a randomly selected subject has both a positive-test-and-a-blood. alcohol·level-higher than 0.05%?. 2. For a randomly selected subject, what is the probability that the test will be positive? 3. Among subjects who have a positive test, what is the probability that·a·subject·has.a.blood. alcohol·level-higher than 0.05%?

If you have a b of 0.56 in a regression equation, what does this mean? For every one-unit increase in x, you get an increase of 0.56 in y r = .31 On average, the variability of real scores around the regression line is 0.56 For every 1 standard deviation increase in x, you get an increase of 0.56 standard deviations in y
