Question

The scatter plot below shows the temperature, in degrees Fahrenheit, and the cups of hot chocolate sold on 14 days throughout the year. Also shown is the line of best fit for the data.

Scatterplot graph: x-axis label is temperature in degrees fahrenheit and y-axis label is cups of hot chocolate; there are 14 points, including (78, 13), (75, 32), (59, 67), and (48, 102); line of best fit passes through points (39, 132) and (42, 125)

For these 14 days, there is _(blank)_ correlation between the temperature and the cups of hot chocolate sold.

Group of answer choices

no

a negative

a positive

Answer 1

For these 14 days, there is a negative correlation between the temperature and the cups of hot chocolate sold.

For these 14 days, there is a negative correlation between the temperature and the cups of hot chocolate sold.

As the temperature decreases, the number of cups of hot chocolate sold tends to increase, indicating an inverse relationship between temperature and hot chocolate sales.

This is supported by the negative slope of the line of best fit, suggesting that colder days are associated with higher hot chocolate sales.

The correlation coefficient would be negative, indicating the direction and strength of the linear relationship between temperature and hot chocolate sales.
