Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. 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

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used.

 

  1. 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.
