(03.05 LC) Mаlаchi is prаcticing math fluency. He has 100 math оperatiоn flashcards with 42 additiоn problem cards, 56 subtraction cards, and 2 multiplication cards. He will time himself to see how fast he can solve the problems on two cards. He chooses his two cards and they are both multiplication cards. Is choosing two multiplication cards likely? Explain by running a simulation.Part A: State the problem or question and assumptions. (2 points)Part B: Describe the process for one repetition, including possible outcomes, assigned representations, and measured variables. (3 points)Part C: Use digits from a table of random digits or use your calculator to perform one repetition. Submit the list of random digits and indicate those that represent multiplication cards. (3 points)Part D: Suppose there were 5 times when both cards selected were multiplication cards after 1,500 repetitions of the simulation. State your conclusions from these results.

(02.04 HC) Pаrrоts cаn develоp cоgnitive issues аs they get older. This may compromise their memory, ability to learn, awareness, sight, and hearing. A researcher wishes to conduct a study to find which of two medicines, Medicine A or Medicine B, is more effective in improving cognitive health. A total of 150 parrots that are at least 12 years old will be randomly selected from sanctuaries around the United States. The researcher will get consent from all owners, treat the parrots for 1 year, and evaluate changes in cognitive health. Part A: How would the study benefit from adding a control group? (2 points)Part B: What is the best way to randomly place the parrots into the Medicine A, Medicine B, and control groups? (4 points)Part C: The researcher wants to use a blocking variable to place the parrots into groups instead of doing it randomly. He decides to block either by breed or sanctuary. Explain which would be the best blocking method. (4 points) (10 points)
