It is commonly believed that the mean body temperature of a healthy adult is
98.6∘F. You are not entirely convinced. You believe that it is not 98.6∘F. You collected data using 43 healthy people and found that they had a mean body temperature of 98.21∘F with a standard deviation of
1.1∘F. Use a 0.05 significance level to test the claim that the mean body temperature of a healthy adult is not 98.6∘F.
Identify the null and alternative hypotheses?
H0 : μ =98.6
H1 : ___ ___

Identify the appropriate significance level.
