The scatterplot above illustrates the densities of seven planetoids, measured in grams per cubic centimeter, about their average distances from the Sun, expressed in astronomical units (AU). A line of best fit is also included in the diagram. An astronomer has discovered a new planetoid located approximately 1.2 AU from the Sun. Based on the line of best fit, which of the following options best approximates the density of this planetoid, measured in grams per cubic centimeter?

A) 4.6

B) 4.1

C) 3.6

D) 5.5

7

Using the following data, create a scatterplot: Hours studied (x-axis): 2, 4, 6, 8, and 10. Test scores (y-axis): 70, 75, 80, 85, and 90. What type of relationship does the scatterplot suggest?

A) A positive nonlinear relationship

B) A negative linear relationship

C) A no correlation

D) A positive linear relationship

8

Based on the line of best fit, represented by the equation ( y = 2x + 10 ), which describes the relationship between the number of hours exercised per week (x) and the number of calories burned (y), how many calories would be burned if a person exercises for 5 hours per week?

A) 25 calories

B) 15 calories

C) 20 calories

9

In a scatterplot that displays the relationship between the number of days absent from school (x-axis) and test scores (y-axis), one point is noticeably far from the others. This point is referred to as an outlier. An outlier can significantly impact data analysis by skewing the results, potentially leading to misleading conclusions about the overall relationship between the two variables.

A) Anomaly; It can distort the line of best fit, influence correlation, impact statistical measures, and potentially lead to misinterpretation of the data

B) An outlier is a point far away from others in a scatterplot, and it can distort the correlation, line of best fit, and summary statistics, leading to inaccurate data analysis.

C) Extrapolation point; It can affect the accuracy of predictions made based on the scatterplot

D) Deviation; It can introduce variability into the data analysis, affecting the reliability of conclusions drawn from the scatterplot

10

A scatter plot illustrates the relationship between the age of a car (x) and its resale value (y). If the line of best fit passes through the point (5, 8000), what would the resale value of a 5-year-old car be according to that line of best fit?

A) $7,000

B) $9,000

C) $6,000

D) $8,000
