A study by researchers at a university addressed the question of whether the mean body temperature of an animal is 99.4°F. Among other data, the researchers obtained the body temperatures of 102 healthy animals. Suppose you want to use those data to decide whether the mean body temperature of healthy animals is less than 99.4°F. Complete parts (a) through (c) below. a. Determine the null hypothesis. Ho: μ (Type an integer or a decimal. Do not round.) b. Determine the alternative hypothesis. H₂:μ (Type an integer or a decimal. Do not round.) c. Classify the hypothesis test as two tailed, left tailed, or right tailed. The hypothesis test is
