The tail length (t cm) and the mass (m grams) for each of eight woodmice were measured. The data is shown in the table. t (cm) 8.5 7.5 8.6 7.3 8.1 7.5 8.0 7.8 m (g) 28 22 26 21 25 20 20 22 a Using the coding x t-7.3 and y = m-20 complete the following table x 1.2 y 8 0 1 0.5 b Find S, Syy and Sy c Calculate the value of the product moment correlation coefficient between x and y. d Write down the product moment correlation coefficient between t and m. e Write down the conclusion that can be drawn about the relationship between tail length and mass of woodmice.
