. A landscape specialist studies the relationship between early-stage (x) and late-stage (y) tree heights. Assume the SLR model. For 5 trees, with 34 inches as the sample mean early-stage height, we know: sx2 = 11.5 , b0 = 36.2 , b1 = 0.9 , SSR = 40.2, and SSE = 9.8. a) Write the estimated SLR equation. b) The p-value for the SLR model utility test is 0.04. Does the evidence suggest a linear relationship between early-stage and late-stage heights? Explain. c) If appropriate, predict the late-stage height when the early-stage height is 35 inches. d) What percentage of variation in late-stage height values is accounted for by the assumed relationship with early-stage heights?

Question
5. A landscape specialist studies the relationship
between early-stage (x) and late-stage (y) tree
heights. Assume the SLR model. For 5 trees, with
34 inches as the sample mean early-stage height,
we know: sx2 = 11.5 , b0 = 36.2 , b1 = 0.9 , SSR = 40.2,
and SSE = 9.8.
a) Write the estimated SLR equation.
b) The p-value for the SLR model utility test is 0.04.
Does the evidence suggest a linear relationship
between early-stage and late-stage heights?
Explain.
c) If appropriate, predict the late-stage height
when the early-stage height is 35 inches.
d) What percentage of variation in late-stage
height values is accounted for by the assumed
relationship with early-stage heights?
