Question: 2. (12 points) (Uses data from section 2.1 exercise 7) The produce yield from the theoretical maximum was studied under various temperatures and stirring speeds.
2. (12 points) (Uses data from section 2.1 exercise 7) The produce yield from the theoretical maximum was studied under various temperatures and stirring speeds. (a) (5 points) Perform a hypothesis test for association between temperature and the yield. (significance 5%) (b) (5 points) Perform a hypothesis test for association between stirring speed and the yield. (significance 5%) (c) (2 points) Find and interpret a 95% confidence interval for the slope of the least squares line for stirring speed vs. yield.
