Scatter Plots Practice Test

A researcher recorded the number of advertisements shown to users in a session and the percentage of users who clicked at least one ad. The scatterplot shows ads shown on the x-axis (ads) and click rate on the y-axis (percent). One point appears to be an outlier. If that outlier were removed, which change would most likely occur to the correlation between ads shown and click rate?

A student measured how much time a phone was used in a day and the phone’s battery percentage remaining at the end of that day. The scatterplot shows usage time on the x-axis (hours) and battery remaining on the y-axis (percent). A line of best fit is shown. What does the slope of the line of best fit represent in this context?
