Show transcribed image text The alcohol content for Guinness draft 4.0% by volume, with standard deviation of 1.8%. One brewmaster wanted er is a brew ferment to see if he could increase the alcohol content by letting the by volume. for an extra week. A sample of 8 batches resulted in an average 5.3% alcohol a. Calculate oM. b. Calculate zobt. c. What is the probability associated with this z score (or more extreme)? d. What is the cut off statisticians usually use to decide whether an outcome is likely or unlikely? e. Is the average of 5.3% alcohol content likely or unlikely in a population with a mean of 4.0%? f what do you conclude about the alcohol content if beer is fermented for an additional week?
