Second load of wash In Exercise 4, we saw a 98% confi-dence interval of (-40, -22) minutes for mTop - mFront , the difference in time it takes top-loading and front-loading 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 thanfront loaders.b) If I choose the laundromat’s top loader, there’s a 98%chance that my clothes will be done faster than if I hadchosen the front loader.c) If I tried more samples of both kinds of washingmachines, in about 98% of these samples I’d expectthe top loaders to be an average of 22 to 40 minutesfaster.d) If I tried more samples, I’d expect about 98% of the resulting confidence intervals to include the true dif-ference in mean cycle time for the two types of wash-ing machines. e) I’m 98% confident that top loaders wash clothes anaverage of 22 to 40 minutes faster than front-loaders.

loading 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 laundromat’s top loader, there’s 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 I’d expect
the top loaders to be an average of 22 to 40 minutes
faster.
