MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis. Professor Ratzo wonders if rats will run a maze faster for some kinds of foods than for others. He randomly assigns 30 rats to one of three conditions, 10 rats to each condition. Group 1 gets buttered bread at the end of the maze, Group 2 gets cheddar cheese, and Group 3 gets honey- glazed ham. The number of seconds each rat took to run the maze is recorded. The hypothesis is that type of food makes a difference in rat running time. Choose the type of test you should use to test this hypothesis? Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).

A shoe company wants to determine if the new tread on its top line of running shoes lasts longer than the original tread. The company recruits 50 runners for a study. Each runner will perform their typical workout wearing one shoe with the original tread on one foot and another shoe with the new tread on the other foot. The foot that wears the new type of tread will be decided by flipping a coin. After one month, the runner will wear the new type of tread on the opposite foot. At the end of the second month, the difference in tread wear (New - Original) will be calculated. What type of sampling is described in this study? What is the appropriate inference procedure? one-sample t-test for μ one-sample z-test for p one-sample t-test for diff two-sample t-test for new original

Briefly state why you think so. Part B Dario decides to take each one of the 4 pieces and share it equally among the 5 of them. First, he divides one piece into 5 equal parts and shares it, then the next one, and so on. What fraction of the party size sub did each person get after all the parts were shared out?
