In a 2007 issue, a magazine examined the relative merits of top-loading and front-loading washing machines, testing samples of several different brands of each type. One of the variables the article reported was the cycle time, defined as the number of minutes it took each machine to wash a load of clothes. Among the machines rated good to excellent, the 98% confidence interval for the difference in the mean cycle time ("top - "front) is (- 47, - 26). Complete parts a) through c) below. a) The endpoints of this confidence interval are negative numbers. What does this indicate? O A. There is probably no difference in mean cycle time between top-loading and front-loading washing machines. O B. The mean cycle time is probably higher for front-loading washing machines than for top-loading machines. O C. The mean cycle time is probably higher for top-loading washing machines than for front-loading machines. b) What does the fact that the confidence interval does not contain 0 indicate? A. It indicates that the difference is not significant. O B. It indicates that the difference is significant. O C. It indicates that the mean cycle time is higher for front-loading washing machines than for top-loading machines. O D. It indicates that the mean cycle time is higher for top-loading washing machines than for front-loading machines.
