1. The fuel economy information on a new SUV window sticker indicates that its new owner can expect 16 mpg (miles per gallon) in city driving and 20 mpg for highway driving and 18 mpg overall. Accurate gasoline records for one such vehicle were kept, and a random sample of mileage per tank of gasoline was collected. 19.0 16.6 19.9 22.8 18.7 18.2 18.0 15.4 19.1 20.5 16.9 20.4 21.6 18.6 20.8 16.5 16.9 16.9 17.9 16.9 19.9 16.1 17.6...

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
