The data in the table below are accelerated life test results on 24 units of a type of sheathed tabular heater. Solve the following question and show your process.

C. (Source: "A short life test for comparing a sample with previous accelerated test results," by Wayne Nelson, Technometrics, 14, 1972, 175-185.) The data in the table below are accelerated life test results on 24 units of a type of sheathed tabular heater. 7 is the temperature in F and Y is the life in hours at that temperature for a single unit. Six units are tested at each temperature. Plot the data and look at them. Fit the model log10 Y = Bo + Bi (1000/(7 + 460)} + and perform all the usual analyses.
