Study One: The cutoff point for hypertension in humans is systolic BP >140 millimeters of mercury. Researchers are interested in finding out whether the mean blood pressure at the baseline of a study is greater than 140. They run a one sample t-test (sample size = 21) and the results (in Stata and R) are shown as below. STATA output ttest sysBlood == 140 One - sample t test Variable Obs Mean Std. err. Std. dev. [95% conf. interval] sysBlood 21 144.76 8.117 141.07 148.46 mean = mean ( sysBlood) t = ??? He: mean = 140 Degrees of freedom = Ha: mean 140 Pr(T |+|) = 0.014 Pr (T > t) = 0.007 R Output > t. test (PartV$sysBlood, mu = 140) One Sample t-test data: Partv$sysBlood t = ??? , df = ??? , p-value = 0.014 alternative hypothesis: true mean is not equal to 140 95 percent confidence interval: 141.07 148.46 sample estimates: mean of x 144.76 > sd (Partv$sysBlood) [1] 8. 117Question 21 {1 point] The alternative hypothesis for this problem Is 0 The mean blood pressure is equal to 140 O The mean blood pressure is less than 140 O The mean blood pressure is gleater than 140 O The mean blood pressure is NOT equal to 140 Question 22 {1 point] The t score in the second table is (round to 3 decimal places]: __ Choose the correct answer from below. Question 23 {1 point] The degree freedom ofthe t distribution that is used in this one-sample t test is: _ Choose the correct answer from below
