A biologist is developing two new strains of bacteria. Each sample of Type I Bacteria produces 16 now viable bacteria, and each sample of Type Il produces 25 new viable bacteria. Altogether, at least 550
new viable bacteria must be produced. At least 30 but not more than 50, of the original samples must
be Type I. Not more than 50 of the samples can be Type Il. A sample of Type I costs $10 and a sample
of Type Il costs $8. How many samples of each should be used to minimize cost?

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?
