Question
Chicago's Department of Business Affairs and Consumer Protection provides monthly reports of all taxi trips in Chicago, tagged with trip distances, trip durations, fare amounts, and tip amounts. Another variable in the Chicago taxi data reports the total paid for the ride. A 90% confidence interval for the difference Hweekday weekend is $0.867 to $2.123. Complete parts a through c. a) The endpoints of this confidence interval are positive numbers. What does that indicate? OA. This suggests that the mean total paid for weekday rides is different from the mean total paid for weekend rides. B. This suggests that there is no difference in the mean total paid for weekday rides and the mean total paid for weekend rides. C. This suggests that the mean total paid for weekday rides is greater than the mean total paid for weekend rides. D. This suggests that the mean total paid for weekday rides is less than the mean total paid for weekend rides. b) What does the fact that the confidence interval does not contain 0 indicate? provides evidence that the difference between the mean total paid for weekday rides and weekend rides different from 0. That is, the difference in sample means is statistically significant. This is c) If we use this confidence interval to test the null hypothesis that Hweekday Hweekend = 0, what is the alpha level that corresponds to this interval? α= (Type an integer or a decimal. Do not round.)
