A study was conducted with vegetarians to see whether the number of grams of protein each ate per day was related to diastolic blood pressure. The data are given here. If there is a significant relationship, predict the diastolic pressure of a vegetarian who consumes 8 grams of protein per day.

Grams x | 4 6.5 5 5.5 8 10 9 8.2 10.5

Pressure y| 73 79 83 82 84 92 88 86 95
