Question 1 5 Not yet answered Points out of 6.00 F Flag question Chocolates and Happiness!!... A bunch of L840 students set out to study the effect of chocolates in alleviating depression. They chose three of the most popular chocolates brands in the world, Lindt, Ghirardelli, and Cadbury and tested their effects on the level of happiness on a scale of 1 to 10, in a group of people diagnosed with clinical depression. Here, we do not consider before-after effects. The score is based on a self-evaluation by the study subjects. In the diagram below, 95% confidence intervals (Cl) on the effect size given by the difference between mean scores between a pair of chocolate brands is given. There are three diagrams, one for each pair of comparison. The green circles indicate the effect size in each case, the orange vertical lines show the 95% CI and the blue curves are the distribution of effect sizes computed for 10,000 resamples using the bootstrap approach. Based on these diagrams, drag and drop the appropriate text to indicate whether a pair of chocolates produce statistically significant difference in the self-evaluation scores.
