1.) A manufacturing process produces bags of cookies. The distribution of content weights of these bags is supposed to be Normal with mean 15.0 oz and standard deviation 0.5 oz. We randomly selected 6 bags of cookies from the
manufacturer and weighed them, finding a sample mean of 14.63 oz.
Do you have evidence to show that the bags are being under-filled? Carry out a test of significance to test your hypothesis and write up a conclusion on what you find out about the cookies.
