The claim is that mean body temperature of healthy adults is less than 98.6 °F.
Sample Data Summary
Statistics: n=106, x̅ = 98.20 °F, s=0.62 °F.
Suppose μ denotes the true mean body temperature of healthy adults and significance level is 0.01.
The hypothesis of interest is as follows:
Question 5 options:
a) H0: μ = 98.6 °F versus H1: μ > 98.6 °F
b) H0: μ = 98.6 °F versus H1: μ < 98.6 °F
c) H0: μ > 98.6 °F versus H1: μ < 98.6 °F
d) Cannot be determined
