Since the slope of the line is negative and points are widely scattered, we expect the correlation to be negative and low to moderate. Hence,
The closest value would be -0.40
Option A is correct.
32. A scatter plot shows data points that are widely scattered around a line that slopes...
5. What would the scatter plot show for data that produce a Pearson correlation of r = +0.88? (1 pt) a. Points clustered close to a line that slopes up to the right b. Points clustered close to a line that slopes down to the right c. Points widely scattered around a line that slopes up to the right d. Points widely scattered around a line that slopes down to the right
A study indicates the correlation coefficient between salt intake and blood pressure is 0.8. If we plot the data points using salt intake as X axis, and blood pressure as Y axis. What will show on the plot? 1. The data points are clustered close to a line that slopes down to the right 2. The data points are clustered close to a line that slopes up to the right 3. The data points are scattered around a line that...
Outliers are usually? Easy to spot on a scatter plot Hard to spot on a scatter plot Not meant to be included on a scatter plot The last three data points to the right A positive straight line relationship: Shows that as the values of y increase, the values of x decrease Shows that as the values of x increases, the values of y decreases Shows that as the values of y decreases, the values of x remain constant Shows...
Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables has a significant correlation.) Then use the regressiorn equation to predict the value of y for each of the given x-values, if meaningful. The table shows the shoe size and heights (in) for 6 men Shoe size: x-T8.5 110T15|130|135 (a) x=size 10 0 (b)x-size 10.5 3.5 745 725(c)x-s size 16.0 (d)x- size...
13 The scatter plot for the data set X and Y shows the data points clustered in a nearly perfect circle. For these data, what is the most likely value for the Pearson r? a) near 0 b) r near +1 c) r near - 1 d) r between - 5 and 7.5 e) none of the above.
Examine the scatter plot. a) Draw a line of best fit through the following data. [1] [1] b) Predict a correlation coefficient that would describe this data. c) Describe how the line of best fit would change without the influential point on the right d) The x-axis is amount of snowfall and the y-axis is cars on the road.

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significa correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The table below shows the heights (in feet) and the number of stories of six notable buildings in a city. Height, x 758 621 518 510 492 483 (a)...
Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The caloric content and the sodium content (in milligrams) for 6 beef hot dogs are shown in the table below. (a)x=180 (b)x=90 (c)x=120 (d)x=50 Calories, x Sodium, y 150 ...
