A medical research team carried out an investigation into the metabolic rate, MR, of men aged between 30 years and 60 years. A random sample of 10 men was taken from this age group. The table below shows for each man his MR and his body mass index, BMI. The table also shows the rank for the level of daily physical activity, DPA, which was assessed by the medical research team. Rank 1 was assigned to the man with the highest level of daily physical activity. [You may use $$\(\left.\quad \mathrm{S}_{x y}=15.1608 \quad \mathrm{~S}_{x x}=6.90181 \quad \mathrm{~S}_{y y}=45.304\right]\)$$ Calculate the value of the product moment correlation coefficient between MR and BMI for these 10 men.
