[All Steps] QUESTIONS 36—38 refer to a researcher at Acme Quality Control studying the output of Acme twelve ounce drinking water from its two bottling
Question: QUESTIONS 36—38 refer to a researcher at Acme Quality Control studying the output of Acme twelve ounce drinking water from its two bottling machines A and B. A sample of 5 bottles from machine A had mean content of 12.4 ounces with sample standard deviation of .15 ounces, whereas a sample of 11 twelve ounce bottles from machine B had a mean content of 12.6 ounces with a standard deviation of .25 ounces.
If we DO assume that both machines have the same standard deviation in the amount of water put in a bottle, then the estimate of that standard deviation which we compute from the researcher’s data is:
