Consider a chemical company which wishes to find out whether a new catalyst, catalyst XA-100, changes the mean hourly yield of its chemical procedure from historical process mean of 745 pounds per hour.
When five trial runs are made using the new catalyst, the following yields (in pounds per hour) are recorded: 810, 804, 748, 863, and 820.
a: Letting µ be the mean of all possible yields using the new catalyst, set up the null and alternative hypotheses required if we wish to attempt to provide evidence that µ differs from 745 pounds.
b: Employ Minitab to find out the mean and standard deviation of sample of 5 catalyst yields. Using a critical value and supposing approximate normality, test the hypotheses you set up in part a: by setting the equal to .01. Find out and interpret the p-value for hypothesis test.
