ro A manufacturer wants to measure the relationship between the sweetness index (y) of peach juice and the amount of water soluble pectin (x) in the juice. Data collected on these two variables for 10 production runs are shown in the table below. y 5.8 6.0 5.8 5.2 5.6 5.9 5.7 5.5 5.3 231 227 259 5.9 210 224 215 231 268 239 218 X i. Compute the Pearson correlation coefficient. ii. Using a 0.01 level of significance, test the hypothesis that there is no relationship between the two variables against the alternative hypothesis that this relationship is negative.
