6. A researcher wishes to see whether there is any difference in the weight gains of athletes following one of three special diets. Athletes are randomly assigned to three groups and placed on the diet for six weeks. The weight gains (in pounds) are shown here. At a = 0.05, can the researcher conclude that there is a difference in the diets? Next, if the null hypothesis is rejected, conduct a post hoc test using Bonferroni to examine which diet is significantly different at 10% probability level. Diet A Diet B Diet C 7 5 8 3 (20 marks)
