A baseball coach gives half his players an energy drink to consume before each game; the other half does not receive the energy drink. After a month of games, he analyzes their playing stats. He concludes the energy drink helped improve their performance on the field. How can the coach test the means to be sure his results are not likely to happen by chance? He can pick players at random and analyze their playing stats without calculating means. He can analyze the two groups by calculating the means and the difference of the means. He can pick the players he wants to analyze based on the best stats. He can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.

Lenny and Thad spend a certain amount of money from their money box each month to buy comic books. The table shows the relationship between the amount of money (y) remaining in Lenny's money box and the number of months (x):Function 1Number of Months(x) Amount Remaining (in dollars)(y)1 752 603 454 30The equation shows the relationship between the amount of money (y) remaining in Thad's money box and the number of months (x): Function 2: y = −12x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $12 each month. Function 2 shows a greater rate of change, because Lenny spends $75 each month and Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $80 each month.
