A study by researchers at a university addressed the question of whether the mean body temperature of an animal is99.8°F. Among other data, the researchers obtained the body temperatures of 100 healthy animals. Suppose youwant to use those data to decide whether the mean body temperature of healthy animals differs from 99.8°F.Complete parts (a) through (c) below.a. Determine the null hypothesis.HoiH(Type an integer or a decimal. Do not round.)
