It has long been stated that the mean temperature of humans is 98.6degrees°F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6degrees°F. They measured the temperatures of 61 healthy adults 1 to 4 times daily for 3 days, obtaining 275 measurements. The sample data resulted in a sample mean of 98.2degrees°F and a sample standard deviation of 1.1degrees°F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6degrees°F at the α=0.01 level of significance. State the hypotheses. H0: ▼ σ p μ ▼ = ≠ > < 98.6degrees°F H1: ▼ μ p σ ▼ < = > ≠ 98.6degrees°F
