A food manufacturing company claims that the actual average protein content in theirprotein bars is 20 grams. To investigate this claim, a sample of 25 protein bars from differentbatches are collected. The average and standard deviation of the samples are measured as18 and 2 grams, respectively. a) Although the manufacturer claims that the average protein content in each bar is 20grams, your hypothesis (seeing the sample average of 18) is that the actual proteincontent should be smaller than 20 grams, with 95% confidence. Investigate yourhypothesis. Based on your conclusion, is the manufacturer’s claim valid?b) Find p-value and make a conclusion based on that.
