2. Lucy is opening several candy stores. The floors of the stores can be pink or green. She wants to determine if the color of the floors affects how much candy people eat. Lucy finds 176 volunteers. She randomly assigns half of them to a room with pink floors and lets them eat as much chocolate as they want for one hour. She assigns the other half to a room with green floors and lets them eat as much sour candy as they want for two hours. Lucy records the total amount of candy eaten in each room. Part A: Which would be an appropriate statistical model for Lucy to use in order to determine if the color of the floor affects how much candy her customer will eat? a. A Sample Survey b. An Experiment c. An Observational Study Part B: Does her model satisfactorily help to answer her question of the effect of floor color on the amount of candy people eat? Why or why not? a. Yes, her model does help to answer his question. She randomly selected individuals and placed them in two different colored rooms b. No, her model does not help to answer her question. The method was not consistent for both randomly selected groups. Part C: Select all of the following that could be considered flaws in Lucy's method. OThere are too many volunteers. O The room assignments were random. O The groups had different types of candy. O The groups had the same number of volunteers. O The groups did not have the same amount of time to eat their candy.
