A local chip manufacturer distributes chips in bags labeled as 150g. A group of consumers believe they are being cheated. They run a test on 32 bags, measures their contents, and obtains a sample mean of 145 grams with a standard deviation of 6 ounces. Use a 0.01 significance level to test the consumer's claim that the company is cheating its customers.
