Question 9: give the hypotheses A statistician is trying to determine if eating a healthy vegetable diet willhelp control blood pressure. The statistician compared 18 people on ahealthy vegetable diet (eat vegetables with every meal) with an averageblood pressure of 123 mmHg and a standard deviation of 10mmHg to 40people who did not have a healthy vegetable diet. The 40 people had anaverage blood pressure of 132mmHg with a standard deviation of 10mmHg. Assume blood pressure values are normally distributed. At the5% significance level determine if the average blood pressure of peopleon a healthy vegetable diet is better than those who are not on one. Takethe people on the vegetable diet as population 1.Give the hypotheses.O Null: There is no difference in the average blood pressure of those that eatvegetables.Alternative: The average blood pressure is lower for those that eat vegetables.Null: There is no difference in the average blood pressure of those that eatvegetables.Alternative: The average blood pressure is higher for those that eat vegetables.Null: There is no difference in the average blood pressure of those that eatvegetables.Alternative: The average blood pressure between those that eat vegetables andthe control group is not equal.
