Refer to the bullfrog data of Exercise 12.3.7. Assuming that the linear model is applicable, estimate the
maximum jump length of a bullfrog whose body length is 150 mm.
Exercise 12.3.7:
Scientists studied the relationship between the length of the body of a bullfrog and how far it can jump.
Eleven bullfrogs were included in the study. The results are given in the table.16
(a) Calculate the linear regression of Y on X.
(b) Interpret the value of the slope of the regression line, b1, in the context of this setting.
(c) What proportion of the variation in maximum jump distances can be explained by the linear relationship
between jump distance and frog length?
(d) Calculate the residual standard deviation and specify the units.
(e) Interpret the value of the residual standard deviation in the context of this setting.
