Question

Spreading rate of spilled liquid. Refer to the chemical engineer progress (January 2005) study of the rate at which a spilled volatile liquid (methanol) will spread across a surface, Excercise 16. Consider a straight line model relating mass of the spill (y) to elapsed time of the spill (x). Use minitab when possible and show work

a. Is there sufficient evidence (at alpha= .05) to indicate that the spill mass (y) tends to diminish linearly as time (x) increases?

b.) Give an interval estimate (with 95% confidence) of the decrease in spill mass for each minute of elapsed time.
