Describe the relationship between the variables. There is no relationship between the variables. As the age increases, the height increases. As the age increases, the height decreases. As the height decreases, the age decreases.

As the age increases, the height increases.

The scatterplot shows the ages and values of cars that residents in a neighborhood own.Which statement about the scatterplot is true? The point (10, 15) shows there is no relationship between the age of a car and the value of a car. By excluding (10, 15), a better description can be given for the data set. By including (10, 15), the description of the data set can be understated. Although (10, 15) is an extreme value, it should be part of the description of the relationship between the age of a car and the value of the car.

By excluding (10, 15), a better description can be given for the data set.

Hugo recorded the height of each plant after he exposed each plant to a set amount of sunlight daily. The scatterplot shows his results after 2 weeks of exposing each plant to a set amount of sunlight.Which statement about the outlier in the data set is true? Hugo should not include the outlier because it lessens the effect of showing that sunlight helps plants grow. Hugo should include the outlier because it shows there is no relationship between hours of sunlight and plant height. Hugo should not include the outlier because it strengthens the effect of showing that sunlight helps plants grow. Hugo should include the outlier because it shows there is a relationship between hours of sunlight and the height of the plant.

Hugo should not include the outlier because it lessens the effect of showing that sunlight helps plants grow.

The scatterplot shows the time that movers spent packing large boxes for a customer.Which statement about the scatterplot is true? The point (2, 10) shows that there is no relationship between the packing time and the number of boxes. Although (2, 10) is an extreme value, it should be part of the description of the relationship between packing time and number of boxes. Including the point (2, 10) could cause the description of the data set to be understated. Including the point (2, 10) could cause the description of the data set to be overstated.

Including the point (2, 10) could cause the description of the data set to be overstated.

A scatterplot is produced to compare the size of a lake to the number of fish that are in it. There are 15 data points, each representing a different lake. The points are widely dispersed on the scatterplot with no pattern of grouping. Interpret what the results of the scatterplot tell you about the relationship between the two variables.

Since there is no cluster formed in the scatterplot, the two variables are not related. Therefore, based on the data shown in the scatterplot, the number of fish in a lake is not dependent on the size of the lake.

Leah claims the data in the table contains a cluster. Why is Leah's statement true? There is no obvious outlier. The y-values are steadily increasing as the x-values are decreasing. The data contains a group of closely occurring points. Leah's statement is not true.

The data contains a group of closely occurring points.

The graph shows the number of Internet downloads of a song compared to the number of times it is played on the radio. What can you conclude from the data? Check all that apply. The number of times a song is played on the radio affects its number of downloads. Increased radio play affects the download demand for all songs equally. Even though there was very high radio play, the downloads of one song remained very low. In general, increased radio play does not affect the number of downloads.

The number of times a song is played on the radio affects its number of downloads. Even though there was very high radio play, the downloads of one song remained very low.

The scatterplot shows the time that some students spent studying and the number of spelling mistakes on an essay test.Which statement about the scatterplot is true? The point (8, 17) can cause the description of the data set to be overstated. Although (8, 17) is an extreme value, it should be part of the description of the relationship between studying time and the number of spelling mistakes. Including the point (8, 17) can cause the description of the data set to be understated. The point (8, 17) shows that there is no relationship between the studying time and the number of spelling mistakes.

The point (8, 17) can cause the description of the data set to be overstated.

The scatterplot below shows a set of data points.Which statement about the scatterplot is true? The scatterplot does not have a cluster, and the variables are not related. The scatterplot does not have a cluster, and the variables are related. As x increases, y increases. The scatterplot has a cluster, and the variables are not related. The scatterplot has a cluster, and the variables are related. As x increases, y increases.

The scatterplot has a cluster, and the variables are related. As x increases, y increases.

Which best describes the data in the table? There are no outliers, but there is a cluster. There is a cluster and outliers. There are no clusters or outliers. There are no clusters, but there are outliers.

There are no outliers, but there is a cluster.

A scatterplot is produced to compare the size of a school building to the number of students at that school who play an instrument. There are 12 data points, each representing a different school. The points are widely dispersed on the scatterplot without a pattern of grouping. Which statement could be true? There is no relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster. As the size of a school building increases, the number of student musicians increases because the scatterplot has a cluster that increases from left to right. As the size of a school building increases, the number of student musicians decreases because the scatterplot has a cluster that decreases from left to right. The size of a school building is equal to the number of students who play an instrument because the scatterplot does not have a cluster.

There is no relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
