Second load of wash In Exercise 4, we saw a 98% confidence interval of (-40, -22) minutes for mTop - mFront, the difference in time it takes top-loading and frontloading washers to do a load of clothes. Explain why you think each of the following statements is true or false: a) 98% of top loaders are 22 to 40 minutes faster than front loaders. b) If I choose the laundromats top loader, theres a 98% chance that my clothes will be done faster than if I had chosen the front loader. c) If I tried more samples of both kinds of washing machines, in about 98% of these samples Id expect the top loaders to be an average of 22 to 40 minutes faster. d) If I tried more samples, Id expect about 98% of the resulting confidence intervals to include the true difference in mean cycle time for the two types of washing machines. e) Im 98% confident that top loaders wash clothes an average of 22 to 40 minutes faster than front-loaders.
