4. Determine the appropriate approach to conduct a hypothesis test for
this claim: The systolic blood pressure of men who run at least five
miles each week varies less than does the systolic blood pressure of all
men. Sample data: n = 100 randomly selected men who run at least five
miles each week, sample mean = 108.4, and s = 20.3
A) Use the normal distribution.
B) Use the Student t distribution.

D) Use nonparametric or bootstrapping methods.
5. Determine the appropriate approach to conduct a hypothesis test for
this claim: The mean sodium content of a 30 g serving of snack crackers
is 2,200 mg. Sample data: n = 130 snack crackers, sample mean= 3,100
mg, and s = 570. The sample data appear to come from a normally
distributed population.
