Question

A study by researchers at a university addressed the question of whether the mean body temperature of an animal is 98.2°F.Among other data, the researchers obtained the body temperatures of 97 healthy animals. Suppose you want to use those data to decide whether the mean body temperature of healthy animals is greater than 98.2°F. Complete parts (a) through (c) below.

a. Determine the null hypothesis.

H0: μ ______ (=, >, < or ≠) ________ ________________ (healthy animals or °F)

(Type an integer or a decimal. Do not round.)

b. Determine the alternative hypothesis.

Ha: μ (=, >, < or ≠) ________ ________________ (healthy animals or °F)

(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 _______________ (right tailed, left tailed or two tailed)
