The age x and resting heart rate y were measured for ten men, with the results shown in the table.
x | 20 | 23 | 30 | 37 | 35 | 45 | 51 | 55 | 60 | 63 |
y | 72 | 71 | 73 | 74 | 74 | 73 | 72 | 79 | 75 | 77 |
Test, at 10% level of significance, whether age is useful for predicting resting heart rate.
