Concept explainers
Perfect shuffle problems (H). Suppose we used our failed perfect shuffling of digits to mix the digits of the numbers (x, y) that describe a point on the square to get a one-toone correspondence with the points on a line segment. What point in the square would be paired with the point
With what point on the line does that point in the square actually get paired? Is this a problem? Explain.

With the following three possible examples of best-fit lines:Line 1 The straight line pass through only two data pointsLine 2 The straight line did not pass through any data pointLine 3 The straight line did not pass through any data point Are each of the following statements true or false?1. no straight line can pass through all data points exactly. a. Trueb. False 2. line 1 does not fit the data points very well because too many points are the the right. a. Trueb. False 3. line 2 does not fit the data points very well because too many points are above the line. a. Trueb. False 4. line 3 does not fit the data points perfectly, but seems to have the best fit of these three lines. a. Trueb. Falsearrow_forwardTwo scatterplots are shown below. Scatterplot 1 A scatterplot has 14 points. The horizontal axis is labeled "x" and has values from 30 to 110. The vertical axis is labeled "y" and has values from 30 to 110. The points are plotted from approximately (55, 60) up and right to approximately (95, 85). The points are somewhat scattered. Scatterplot 2 A scatterplot has 10 points. The horizontal axis is labeled "x" and has values from 30 to 110. The vertical axis is labeled "y" and has values from 30 to 110. The points are plotted from approximately (55, 55) steeply up and right to approximately (70, 90), and then steeply down and right to approximately (85, 60). The points are somewhat scattered. Explain why it makes sense to use the least-squares line to summarize the relationship between x and y for one of these data sets but not the other. Scatterplot 1 seems to show a relationship between x and y, while Scatterplot 2 shows a relationship between the two variables. So it makes sense to use…arrow_forward
