Carson invested $3,900 in an account paying an interest rate of 2.1% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 14 years?

Can someone answer this question? : )

Need asap. solve for the following inequality

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.
