A special diet is intended to reduce systolic blood pressure among patients diagnosed with stage 2 hypertension. If the diet is effective, the target is to have the average systolic blood pressure of this group be below 150. After six months on the diet, an SRS of 28 patients had an average systolic blood pressure of = 142 with standard deviations = 20. A one sample t-test is conducted to determine if this is sufficient evidence that the diet is effective. What is the value of the one-sample t-test statistic? Round your answer to three decimal places.
