B . . 1EX How well does the number of cups of coffee a student drinks predict his or her caffeine content? 5 1 Sixteen student volunteers at Ohio State University drank a randomly assigned number of cups of of the data appears below. coffee. Thirty minutes later, the caffeine content was measured in their blood levels. A scatterplot 8 0.25 0.20 0.15 Caffeine Content 0.10 O 0.05 O OO 0.00 + 3 10 Cups of Coffee 8. What does the scatterplot reveal? State in plain language as if you were explaining to a friend who knows very little statistics. the scatterplot shows that there is a generally positive correlation between blood, caffeine levels and the quantity of coffee, a person drinks. The amount of caffeine in the coffee tends to rise with the quantity consumed, although there is a variation in the amount of caffeine in a given number of cups of coffee, resulting in the connection, not being exactly linear the relationship between the two variables of the quantity consumed, and the amount of caffeine in the blood is visually depicted in the scatterplot which we can observe. 9.

State your best guess for the correlation coefficient (r) of the scatterplot above. 6 a statistical measure used to quantify the strength and direction of a linear relationship between two variables is the correlation R. The scatter plot shows that where caffeine rises so does the number of cups consumed the dispersed points surrounding the trend indicates a non-linear relationship although it is still very strong. The correlation coefficient should be in the range of about 0.72 0.9 which is a strong positive linear relationship, this could potentially count to 81% of the variability in caffeine level. Overall, the scatterplot shows a strong positive linear relationship between caffeine content and the number of cups of coffee drank. 10. Using your guess above, describe the correlation coefficient. a correlation coefficient of 0.7 shows that the number of cups of coffee drink accounts for roughly 49% of the variability in the caffeine concentration similarly the 0.9 means that the cup of coffee may count for 81% of the variability in caffeine level showing a strong correlation. The correlation coefficient places a number between -1 and one that shows the strength of correlation. relationship between two situations. I got these percentages by squaring the strength of 11. Estimating your points, use Desmos to generate the equation of the best fit line using the linear regression feature. Type the regression equation in the space below.
