Answer to Question #174708 in General Chemistry for Mitra

Question

The company G wants to extract Betulin from birch bark with the help of leaching. 2 research groups, E and F, propose two different processes.

The group E thinks that you should use pressurized reflux. 
The group F proposes classic reflux cooking which is both less advanced and cheaper than E's process. 
In order to investigate which method to use, several leaching performed both methods and analyzed the yields of the processes (%), see below
E yields [%]: 13, 18, 12, 14, 13, 12, 13
F yields [%]: 10, 11 , 15, 14, 13, 14, 13, 12


a) Show if there is a significant (95%) difference in precision between the processes? 
B) Show if there is any significant (95%) difference in the yield between the processes? 
C) Construct a 95% confidence interval for the F's process exchange? 
d) Which method should company use? Motivate your answer.
