Paired t-test for proportions
WebThe value of the test statistic is: t = − 14.4 − 0 6.77 / 10 = − 6.73. The critical region approach tells us to reject the null hypothesis at the α = 0.01 level if t > t 0.005, 9 = 3.25 or if t < t 0.005, 9 = − 3.25. Therefore, we reject the null hypothesis because t = − 6.73 < − 3.25, and therefore falls in the rejection region. WebWe will use the sampling distribution of p ^ 1 − p ^ 2 as we did for the confidence interval. For a test for two proportions, we are interested in the difference between two groups. If the difference is zero, then they are not different (i.e., they are equal). Therefore, the null hypothesis will always be: H 0: p 1 − p 2 = 0.

WebOct 20, 2016 · First we might want to run a test to see if we can statistically conclude that not all proportions are equal. We can do this with the prop.test function. The prop.test function requires that Yes (or “success”) counts be in the first column of a table and No (or “failure”) counts in the second column. Thus we switch the columns using subsetting … WebPaired samples t-tests typically consist of a sample of matched pairs of similar units, or one group of units that has been tested twice (a "repeated measures" t-test).
