Form a conclusion about statistical significance. Do not make any formal calculations. Either use the results provided or make subjective judgments about the results. A researcher investigated whether following a vegetarian diet could help to reduce blood pressure. For a sample of 85 poiple who followed a vegetarian diet for 4 months, the mean systolic blood pressure was 124 mmHh. For a sample of 75 people who followed a non-vegetarian diet for 4 months, the mean systolic blood pressure was 138 mmHg. Methods of statistics show that if a vegetarian diet had no effect on blood pressure, there would be less than 1 chance in 100 of getting these results. Does the result have statistical significance? Why or why not? Does the result have practical significance? (4 pts)
