Find critical value and compute the test value as well

Overweight Dogs A veterinary nutritionist developed a diet for overweight dogs. The total volume of food consumed remains the same, but onehalf of the dog food is replaced with a lowcalorie 'ller" such as canned green beans. Nine overweight dogs were randomly selected from her practice and were put on this program. Their inib'al weights were recorded, and then they were weighed again after 4 weeks. At die 0.05 level of signicance, can it be concluded that the dogs lost weight? Assume the variables are normally distributed.
