Question 2 > 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. If you are going to test this claim at the 0.01 significance level, what would be your null and alternative hypotheses? Ho: 2 H₁: 2 What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O left-tailed Oright-tailed Otwo-tailed
Question 3 > According to the Centers of Disease Control, about 22% of American young people between the ages of 12 and 19 are obese. A student claims that the students his local schools are in better shape than the national average, so their proportion of obese students is less than 22%. . Which are the appropriate null and alternative hypotheses for this study? Ọ Ho: P * 0, H: P =0 Ọ Ho: p = 22%, H: p = 22% O Hg: P = 22%, H: P - 22% O Hp: P = 22%, H: p = 22% . Suppose that the result of the statistical is to fail to reject Ho Which is the proper conclusion? O There is not sufficient evidence to conclude that the students at his local schools have a smaller true proportion of obese students. O There is sufficient evidence to conclude that the students his local schools have a smaller true proportion of obese students. O There is not sufficient evidence to conclude that the students at his local schools have a smaller sample proportion of obese students. O There is sufficient evidence to conclude that the students his local schools have a smaller sample proportion of obese students.
