2) Claim: The average income for college students is below $10,000. a) What would the null and alternative hypotheses be for this test? Họ: HA: b) Explain what a Type 1 error would be for this test. c) What would the decision rule for this test be? d) Suppose that a survey of 450 students had an average of $9550 with a standard deviation of $6000. However, the sample data suggests that the population has a distribution that is not normal. What would the p-value be for this test? (Show your work.) e) Given an interpretation of what the p-value means in the context of the problem. f) If a = 0.05, state a conclusion. %3D
