A study aims to determine if a diet supplemented with phytase has a greater effect from the diet with no phytase on the weight gain (kg) of the broilers. A random sample of 10 broilers were fed with the diet supplemented with phytase and another random sample of 10 broilers were fed with the diet without phytase. After a week, the weight of all the broilers were collected, then the weight gain (kg) was computed. (Use diet with phytase – diet without phytase in your computations) Provide answers to the following: a. The samples are (related/independent) samples. b. At 5% alpha, perform test(s) to determine which test procedure should be used to compare the two populations involved. For EACH test, indicate the following:
