Construct a stem-and-leaf plot of the test scores 67, 72, 85, 75, 89, 89, 87, 90, 98, 100. How does the stem-and-leaf plot show the distribution of these data? Construct the stem-and-leaf plot. Choose the correct answer below. O A. O B. O C. O D. Stem Leaves Stem Leaves Stem Leaves Stem Leaves 6 7 6 7 6 5 6 7 26 7 25 7 25 25 8 5697 8 5996 8 5997 8 5799 9 09 9 08 9 07 9 08 10 0 10 0 10 10 0 How does the stem-and-leaf plot show the distribution of these data? O A. The lengths of the rows are similar to the heights of bars in a histogram; longer rows of data correspond to higher frequencies. O B. The lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to smaller frequencies. O C. The lengths of the rows are similar to the heights of bars in a histogram; longer rows of data correspond to smaller frequencies. O D. The lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to higher frequencies.The table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. Use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation? Weight (Ib) 2915 3140 3815 3970 4115 2040 3440 Highway (mpg) 34 31 27 25 23 39 29 Which scatterplot below shows the data? O A. O B. O C.

O A. Yes, as the weight increases the highway mileage increases. O B. Yes, as the weight increases the highway mileage decreases. O C. No, there appears to be a relationship, but it is not linear. relationakinIs there a linear relationship between weight and highway mileage? O A.
