which form of kepler’s third law can you use to relate the period t and radius r of a planet in our solar system as long as the unit year is used for the period and the astronomical unit is used for the radius?

t²=r³

t²=r

t=r²

t³=r²

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
