Brewing Tea ~ A tea manufacturer claims that their green tea bags contain 2.3 grams of tea per bag. The new factory manager tests this claim byrandomly sampling 8 tea bags and weighing their contents. If the mean weight of the sample bags is less than 1.9 grams, then the machines used to fillthe tea bags will be investigated and repaired. Repeated testing has determined that the weight of these tea bags is normally distributed and has aknown standard deviation of 0.5 grams.The testable hypotheses in this situation are Ho : µ = 2.3 vs. Ha : µ < 2.3 1. Using the same decision rule, what is the power of this test if the actual mean strength of manufactured tea bags is 2.15 per cup? Round youranswer to four decimal places. 0.1981

The power can be calculated as Power = P(reject Ho | alternative is true) It is given that Sample…
