A statistician is trying to determine if eating a healthy vegetable diet will help control blood pressure. The statistician compared 18 people on a healthy vegetable diet (eat vegetables with every meal) with an average blood pressure of 123 mmHg and a standard deviation of 10mmHg to 40 people who did not have a healthy vegetable diet. The 40 people had an average blood pressure of 132mmHg with a standard deviation of 10 mmHg. Assume blood pressure values are normally distributed. At the 5% significance level determine if the average blood pressure of people on a healthy vegetable diet is better than those who are not on one. Take the people on the vegetable diet as population 1.
