I only 1 minute left on my test! In the figure, the hexagon with the “R” is colored red, and each of the other hexagons will be colored red, yellow or green, so that no two hexagons with a common side are the same color. In how many different ways can the figure be colored?

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.
