LSPILL 11.64 SPREADING RATE OF SPILLED LIQUID. Refer to the Chemical Engineering Progress (January 2005) study of the rate at which a spilled volatile liquid will spread across a surface, Exercise 11.30 (p. 644). Recall that the data on mass of the spill and elapsed time of the spill are saved in the file. Is there sufficient evidence (at a = .05) to indicate that the mass of the spill tends to diminish linearly as time increases? If so, give an interval estimate (with 95% confidence) of the decrease in spill mass for each minute of elapsed time.
