In testing two different types of golf clubs, you hit 70 balls with different brands. Using the Brand A nine-iron, you hit your target 56 out of the 70 times. Using the Brand B nine-iron, you hit 70 balls and hit the target only 40 times. You would like to test the claim that the Brand A nine-iron is a more accurate club than Brand B. You want your test to be valid and reliable. What criteria must first be met and explain whether you believe each criteria is met?
