Final answer:
The correct Alternative Hypothesis for looking for evidence that the population mean cholesterol level is too high would be μ > 200 mg/dL, indicating a right-tailed test.
Therefore, the option B is correct.
Step-by-step explanation:
If we are seeking evidence that the population mean cholesterol level (μ) is too high, the Alternative Hypothesis in terms of μ would be μ > 200 mg/dL. This is because we are looking for evidence that the mean is greater than a certain value, which indicates that we would be conducting a right-tailed test. Option B, μ>200 mg/dL, is the correct Alternative Hypothesis.
