Question

I need the right answer to d, e, and f ASAP, please.

The table lists chest sizes (distance around chest in inches) and weights (pounds) of bears. Chest (inches) 26 45 54 49 35 41 41 a. Construct a scatterplot. b. Compute and plot the least-squares regression line. Enter the equation in y = mx + b form. Round to 3 decimal places if needed. y = 8.71 +6.9245x Slope = c. What is the slope of the least-squares regression line (including units). Interpret the meaning of the slope in this situation. 6.9245 Interpretation: 1 Weight (pounds) 210 394 416 308 266 200 282 X Units Weight (pounds) The weight will be increased by 6.9245 pounds. Chest size (inches) ✓ d. Predict the weight of a bear with chest size 60 inches. 424.18 X e. Compute the correlation coefficient r. r = 0.75 X f. Compute the coefficient of determination 2. Interpret what it means in this situation. r² = 0.56
