4. A researcher wishes to determine whether the blood pressure of vegetarians is, on average, lower than the blood pressure of nonvegetarians. Independent simple random samples of 85 vegetarians and 75 nonvegetarians yielded the following sample statistics for systolic blood pressure. Test the claim that vegetarians have lower blood pressure than non vegetarians. Use a 0.05 level of significance. Vegetarians Non Vegetarians n=85 n=75 Mean=124.1mmHg Mean=138.7mmHg St dev=38.7mmHg St dev=39.2mmHg Null and alternative hypothesis (give both in symbolic form and sentence form): Test statistic and p-value (show the calculation or show what you entered into the calculator (screenshots are ok here)): Technical conclusion, circle one: reject the null hypothesis or fail to reject the null hypothesis Nontechnical conclusion addressing the original claim
