If you were going to gather some statistics to create a scatter plot, draw a line of best fit, and interpret the slope and y-intercept in context, which of these would be a good statistical question to ask that apply.
(select two answers)
A. How is college student enrollment changing over the last century?
B. What is your favorite color?
C. What kind of car does your family drive?
D. What percentage of families in Florida had a radio in 1930?

A and D would be good statistical questions to ask.
A. How is college student enrollment changing over the last century?
This question would allow for data to be collected over time to analyze the changes in college student enrollment. The data could be used to create a scatter plot and draw a line of best fit to show the overall trend.
D. What percentage of families in Florida had a radio in 1930?
This question would allow for data to be collected on the percentage of families in Florida that had a radio in 1930. The data could be used to create a scatter plot and draw a line of best fit to show the relationship between the year (independent variable) and the percentage of families with a radio (dependent variable). The slope and y-intercept of the line of best fit could then be interpreted in the context of the question.
