A large test statisticFtells us that the sample means _______ the data within the individual samples, which would be unlikely if the populations means really were equal (as the null hypothesis claims).

Question 12 options:

c)

d)

A golfer wished to find a ball that would travel more than 180 yards when hit with his 5-iron with a club speed of 90 miles per hour. He had a golf equipment lab test a low-compression ball by having a robot swing his club 7 times at the required speed. State the null and alternative hypotheses for this test.

Question 6 options:

a)

H₀: = 180; H_a: > 180

b)

H₀: > 180; H_a: > 180

c)

H₀: < 180; H_a: > 180

d)

H₀: = 180; H_a: < 180
