t is the t-test statistic value (t = 20.88), df is the degrees of freedom (df= 9), p-value is the significance level of the t-test (p-value = 6.210^{-9}). conf.int is the confidence interval (conf.int) of the mean differences at 95% is also shown (conf.int= [173.42, 21...
Step 3: Based on the significance level you chose and the type of tail, you find the critical t-statistics by either looking at a t-distribution table or use a calculator or Excel. Then, you clearly state your rejection region Step 4: You compute the t-statistic using the formula specifi...
The test statistic is based on the median of the differences of the paired observations across the two samples, and can be used on non-normal data. The test makes the following assumptions: The data are continuous numeric. The units are randomly sampled. ...
