A study lооked аt whether а brief diet interventiоn might improve depression symptoms. In the study, 75 college-аge students with elevated depression symptoms and relatively poor diet habits were randomly assigned to either a healthy diet group or a control group. Depression levels were measured at the beginning of the experiment and then again three weeks later. The response variable is the reduction in depression level (as measured by the researchers) at the end of the study. Larger numbers mean more improvement in depression symptoms. The average change in the healthy diet group was 7.87 units. The average change in the control group was 0.76 units. Set up the null and alternative hypotheses to test whether these experimental results allow us to conclude that, on average, improvement of depression symptoms is higher for those who eat a healthy diet for three weeks than for those who don't. Let Group 1 represent those with a healthy diet and Group 2 represent those with no diet change.
