Problem 13SE

Monitoring the yield of a particular chemical reaction at various reaction vessel temperatures produces the results shown in the following table.

 Temp. (°C) Yield (%) Temp. (°C) Yield (%) 150 77.4 250 88.9 150 76.7 250 89.2 150 78.2 250 89.7 200 84.1 300 94.8 200 84.5 300 94.7 200 83.7 300 95.9

a. Find the least-squares estimates for β0, β1, and σ2 for the simple linear model Yield = β0 + β1 Temp + ε.

b. Can you conclude that β0 is not equal to 0?

c. Can you conclude that β1 is not equal to 0?

d. Make a residual plot. Does the linear model seem appropriate?

e. Find a 95% confidence interval for the slope.

f. Find a 95% confidence interval for the mean yield at a temperature of 225°C.

g. Find a 95% prediction interval for a yield at a temperature of 225°C.
