Ten eggplants were chosen at random from his garden and the results recorded: Height (cm) No. of Fruits Produced (x) (y) 28 34 24 29 23 37 31 41 22 25 27 35 29 39 26 33 25 27 a) Compute for the value , b) Described the relationship between the height and the number of fruits produced by the eggplant. 9. With reference to the preceding exercise, test the significance of the computed r, at the 0.05 level of significance. 10. Compute for the value of r for the given data in number 8 and use the t-ratio to test the null hypothesis r = 0, at the 0.01 level of significance
