Question:

66 Spreading rate of spilled liquid. Refer to the Chemical Engineering Progress (Jan. 2005) study of the rate at which a spilled volatile liquid will spread across a surface, Exercise 31 . Recall that the data on mass of the spill and elapsed time is saved in the LIQUIDSPILL file. Is there sufficient evidence (at a = .05 ) to indicate that the mass of the spill tends to diminish linearly as elapsed time increases?

If so, give an interval estimate (with 95% confidence)

of the decrease in spill mass for each minute of elapsed time.
