Unformatted text preview: : Horticulturist Flora Plentie has been studying the relationship between the age X of a papaya tree and its height Y. Her latest data is shown below: X (age) 1 2 3 4 5 Y (ht.) 5 7 9 10 14 2. Test the linearity of the relationship between X and Y, that is, test the hypothesis H : ρ = 0 against H 1 : ≠ at significance level .05. 3. Assume that the hypothesis H : = 0 above has been rejected. Obtain the least squares regression line for predicting the height Y of a 15 year old papaya tree on the basis of its age X. What is your prediction for the height of a 3 and ½ year old papaya tree?...
