Which of the following can we conclude from these facts?A)The correlation between beer sales and ice cream sales is negative.B)For a lot of people, drinking beer causes a desire for ice cream, or vice versa.C)A scatterplot of monthly ice cream sales versus monthly beer sales would show thata straight line describes the pattern in the plot, but it would have to be a horizontal line.D)None of the answer options is correct

Answer 1

D) None of the answer options is correct.

Step-by-step explanation:

None of the options presented here are correct. In this study, we see that months that see high ice cream sales also see high beer sales. However, this does not necessarily mean that there is a strong connection between the sale of ice cream and the sale of beer. Instead, we would need to conduct more research to find out whether a spurious relation exists between these two items. This means that there might be a lurking variable causing higher beer and ice cream sales during some months and lower beer and ice cream sales during other months, such as the weather.

Answer 2

Answer:D

Step-by-step explanation:

The above describes a positive correlation where x and y increase together proportionately therefore an increase in x means an increase in y. None of the options describes a positive correlation.
