In June 2007, Consumer Reports examined top-loading and front-loading washing machines, testing samples of several different brands of each type. One of the variables the article reported on was “cycle time,” 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 mean cycle time (top – front) is (–40, –22). a) Explain what this interval means about the two types of washers.

Explain why you think each of the following statements is true or false:

b) 98% of top loaders are 22 to 40 minutes faster than front loaders.

c) 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.

d) If I tried more samples of both kinds of washing machines, in about 98% of theses samples I’d expect the top loaders to be an average of 22 to 40 minutes faster.

e) If I tried more samples, I’d expect about 98% of the resulting confidence intervals to include the true difference in mean cycle time for the two types of washing machines.

f) I am 98% confident that top loaders wash clothes an average of 22 to 40 minutes faster than front-loaders.

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
