Question # 1
Different hypothesis tests use different test statistics based on the _______ assumed in the null hypothesis.
Question # 2
If men predisposed to heart disease have a mean cholesterol level of 300 with a standard deviation of 30, above what cholesterol level should you diagnose men as predisposed to heart disease if you want the probability of a type II error to be 1%? (The null hypothesis is that a person is not predisposed to heart disease.)

Let X be normal random variable with mean μ and variance 4. For the following hypothesis test H0:μ=1vs.Ha:μ=2, we reject H0 as X≥3. Calculate α, the probability of making Type I error.
Question # 4
