A number of people were asked how many hours each week they spend on the internet. Their results were graphed against their age in the scatter plot and a strong negative correlation was observed. A line of good fit has been drawn in.

The following graph shows the number of internet users (per 100 people) and the breast cancer deaths (per 100,000 women) in 23 countries.Use the scatterplot to select the most correct response about the relationship between number of internet users and breast cancer deaths.Group of answer choicesBecause the slope of the line is positive we can say that higher breast cancer death rates cause higher numbers of internet users.The graph shows no relationship between the number of internet users and breast cancer death rates, so we cannot say that higher numbers of internet users causes higher breast cancer death rates.Because there is a strong linear correlation we can say that higher breast cancer death rates cause higher numbers of internet users.Because there is a positive linear relationship between the number of internet users and breast cancer deaths, we can say that higher numbers of internet users causes higher breast cancer death rates.There is a positive linear relationship between the number of internet users and breast cancer death rates, but we cannot say that higher numbers of internet users causes higher breast cancer death rates.
