Suppose that we want to know how many hours of TV per day (on average) a university student watches. We take a sample and find that the 99% CI for the true mean is (3.0, 3.4). Assume that the common belief is that the mean number of hours of TV is 3.5 per day. Hence, H₀: = 3.5. We disagree with this claim, so H₁: 3.5. Use the 99% CI to test the hypotheses
