The concentration of an active ingredient in the output of a chemical reaction is strongly influenced by the catalyst that is used in the reaction. It is felt that when catalyst A is used, the population mean concentration exceeds 67%. The standard deviation is known to be o = 5%. A sample of outputs from 30 independent experiments gives the average concentration of XA = 66.5%. a. Does this sample information with an average concentration of X4 = 66.5% provide disturbing information that perhaps µ is not 67%, but less than 67%? Support your answer with a probability statement. What is that probability? b. Suppose a similar experiment is done with the use of another catalyst, catalyst B. The standard deviation is still assumed to be 5% and XB turns out to be 72%. Comment on whether or not the sample information on catalyst B strongly suggest that µg is truly greater than Ha. Support your answer by computing P(XB - XA 2 5.5| HB = HA Place your comments/interpretations in your solution file/s.
