9. Consider an experiment in which adult laboratory mice were fed one of three diets: high fat, low fat, and a control diet. The mice were weighed, received these diets for 2 weeks, and then were weighed again. The table below shows the results of the experiment. Diet Gained weight Lost weight High Fat 79 21 Low Fat 30 69 Control 70 30 Assuming a null hypothesis of no relationship between diet and weight gain, determine the expected (row i total)xcolumn / total number in each of the groups (Show work. Expu = sample size Gained weight Lost weight Total (row). High Fat (Observed) 79 21 High Fat (Expected) Low Fat (Observed) 30 69 Low Fat (Expected) Control (Observed) 70 30 Control (Expected) Total (column) Carry out a x Contingency test and make the necessary decision and detailed conclusion (that includes the sample size, test statistic, degrees of freedom, and the P-value).
