interpret results 2. Because the Box's test of equality of variances (P = 295) and the Levine's test (p =.451 and p = .474) are not significant, we can do a MANOVA test. We find that the dietary intervention has a significant impact on weight loss (p =.007) and cholesterol level (p = .000), and the exercise intervention has a significant impact on cholesterol level (p = .006). In addition, there is significant interaction between diet and exercise on weight loss (p = .000).from spss A researcher is interested in the impact of a dietary intervention and/or exercise intervention on weight loss and cholesterol level. Study participants are randomly assigned to receive the dietary intervention and/or the exercise intervention. The data are given in the following table. Use MANOVA to evaluate the impact of the two interventions on the two outcomes, and determine whether there is an interaction effect
