- 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). Z-test O single sample t-test dependent t-test independent t-test Pearson correlation t-test ANOVA Chi-Square Goodness of Fit Test O Chi-Square Test of Independence O Ho: µ1 - P2 = 0 H1: P1 - P2 # 0 O Ho: H1 - P2 <0You are given the chance to play one of two games: One where there is a 20% chance of you winning 8 dollars and an 80% chance of winning 128 dollars.

- jared is opening several ice cream stores. The walls of the stores can be yellow or blue. He wants to determine if the color of the walls affects how much ice cream people eat.
