Do bathroom scales tend to underestimate a person's true weight? A 150 lb test weight was placed on each of 50 bathroom scales.The readings on 26 of the scales were too light, and the readings on the other 24 were too heavy. Can you conclude that more thanhalf of bathroom scales underestimate weight? Find the P-value and state a conclusion.The P-value is 0.2843. Round the answer to four decimal places.We cannotconclude that more than half of bathroom scales underestimate weight.

A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity.
