Mr. Jensen told his class that he plays basketball frequently, and he claimed that he could make 80\%80%80, percent of his free-throw attempts. The class suspected that Mr. Jensen was actually less than an 80\%80%80, percent free-throw shooter. To test their theory, they had Mr. Jensen shoot a series of 404040 free-throws. He made \hat p=60\% p ^ =60%p, with, hat, on top, equals, 60, percent of them. To see how likely a sample like this was to happen by random chance alone, the class performed a simulation. They simulated 100100100 samples of n=40n=40n, equals, 40 free-throws, where each free-throw had an 80\%80%80, percent chance of being made. They recorded the proportion of free-throws made in each sample. Here are the sample proportions from their 100100100 samples

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
