Question
2. Monosodium Glutamate (MSG) had been considered to induce obesity in rodents and mice. In line with this, a study was conducted
to determine the effect of the amount of MSG in the body-weight of mouse. A total of 14 experimental mice were used in the study.
The first set of seven mice received an amount of 5 mg MSG/body-weight while the other set of seven mice received an amount of 15
mg MSG/body-weight of MSG. The initial weight of mice and weight two weeks after injection of MSG were observed. The observations
are summarized in the tables below.
