1) A potato chip manufacturer has been accused of shortchanging their customers with their 10-ounce bags of potato chips. A sample of 50 of that company’s 10-ounce bags was taken, and it was found that the average weight was 9.8 ounces with a standard deviation of 0.3 ounces. Can we conclude that the company’s bags of potato chips are less than 10 ounces? Use a 5% significance level.
