Question

16 . The scatterplot below shows the relationship between the body weights (measured in kg) and heart weights (measured in g) of 144 domestic cats. Also provided is a portion of the regression output. which of the below is correct?

heart weight (g) 20 16 18 10 14 12 8 Coefficients: Estimate Std. Error tvalue Pre-1t1) Bwt 4.0341 0.2503 16.119

Answer 1
