Eight people were on a special diet to lose weight. We are testing to see if the diet actually works. We are going to do a Wilcoxon test. Please calculate the Wilcoxon T statistic. The critical value is 3. It is a two-tailed test with α = .05. Then come to a conclusion about the effectiveness of the diet. The data is:
Before: 253 196 155 234 133 181 295 235
After: 190 144 125 180 115 191 160 232
The null hypothesis is rejected hence we can see that there is effectiveness of the diet
