The following data is representative of that reported in an article with x = burner-area liberation rate (MBtu/hr-ft2) and y = NOx emission rate (ppm):

x 100 125 125 150 150 200 200 250 250 300 300 350 400 400
y 140 150 170 220 200 330 290 400 420 430 390 610 600 660

a. State the appropriate null and alternative hypotheses.

b. Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.)

c. Compute a 95% CI for the expected change in emission rate associated with a 10 MBtu/hr-ft2 increase in liberation rate. (Round your answers to two decimal places.)

A hotel has 8 air conditioners that each have a pre- determined area liberation rate. The carbon dioxide (COx) emission rates (in ppm) are measured for each. The pollution rate is expected to be a linear function of the area liberation rate. (a) Write out the equation of the regression line. Interpret the slope and intercept in the context of this problem. Do they make sense? Include a scatter plot of the data with the correct regression line added. (b)...
