Weight control is a serious issue for packaging of food stuffs. If more than 30% of a production run are under filled then the production run must be redone. A single production run makes 600 packages (the population). A quality control inspector at a large food packaging plant simply just selects the first 50 packages produced that day to weigh and finds 12 of them are under filled. What assumption did the inspector violate that will stop them from doing a hypothesis test

Amanufacturing firm has been averaging 16.8 orders per week for several years. however, during a recession, orders appeared to slow. suppose the firm’s production manager randomly samples 31 weeks and finds an average of 15.6 orders with a standard deviation of 2.3 orders. using a 0.025 significance level, test whether the mean number of orders has decreased. type the full 5 step procedure into the answer box, then for multiple choice practice, answer the following: 1. what is the name and symbol of the parameter that you are testing? 2. what is the symbol and value of the point estimate of that parameter? 3. what distribution are you using to test this parameter? 4. what is the critical value? 5. what is the test statistic value? 6. what is the p-value?
