Acomputer had 2 gigabytes of data stored on it when jackie bought it, and she is storing an additional 3.5 gigabytes per year, as shown in the table below. which of these statements is correct about the linear function that represents this situation? amount of data stored on jackie’s computer time (year) 0 1 2 3 4 gigabytes of data 2 2 + 3.5 = 5.5 5.5 + 3.5 = 9 9 + 3.5 = 12.5 12.5 + 3.5 = 16

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.
