Intro to Stats lab 11 through minitab express. Please and thank you in advance!
Lab 11 In this lab we will perform testing of hypotheses related to the population mean. This material is in Section 13.2. Download the worksheets for this lab, fillA.mtw, fillB.mtw, and fillC.mtw, from LON-CAPA to your computer. Three national bottling companies distribute cans of soft drinks labeled as containing 16 oz. We take the view that, to save money, they may put slightly less in each can, on average, so we'll test Ho : u = 16 vs. H,: uOpen Worksheet to load the data from fill_A.mtw. We test fill levels across all 50 states, and then check how many states incorrectly reject the null hypothesis. 1. Which hypothesis is true for company A, H, or HZ? [Hint: This is easy.] 2. If we retain Ho for company A, then we make (circle one) a correct decision / type II error. 3. If we reject H, for company A, then we make (circle one) a correct decision / type I error. we reject no 101 ompany A, then we type error. Use Statistics>1-Sample Inference>t and select C1 for the sample to perform a hypothesis test for state 1. Check the field perform hypothesis test, and enter value 16 into the "hypothesized mean field. We would like to test H, :u= 16 vs. He: u Open Worksheet to load the data from fill_B.mtw. We test fill levels across all 50 states, and then we check how many states incorrectly retain the null hypothesis. 10. Which hypothesis is true for company B, H, or HZ? 11. If we retain Ho for company B, then we make (circle one) 12. If we reject H, for company B, then we make (circle one) a correct decision / type II error. a correct decision / type I error. Use Statistics>1-Sample Inference>t and select C1 for the sample to perform a hypothesis test for state 1. Check the field perform hypothesis test, and enter value 16 into the hypothesized mean field. We would like to test H, :u= 16 vs. H,: uOpen Worksheet to load the data from fill_C.mtw. We test fill levels across all 50 states, and then we check how many states incorrectly retain the null hypothesis. 15. Which hypothesis is true for company C, H, or HZ? 16. If we retain Ho for company C, then we make (circle one) 17. If we reject H, for company C, then we make (circle one) a correct decision/type II error. a correct decision / type I error. Use Statistics>1-Sample Inference>t and select C1 for the sample to perform a hypothesis test for state 1.
