Refer to the previous exercise. When we test H0: μ = 0 against Ha: μ > 0, we get a P-value of
a. What would the decision be for a significance level of 0.05? Interpret in context.
b. If the decision in part a is in error, what type of error is it?
c. Suppose the significance level were instead 0.01. What decision would you make, and if it is in error, what type of error is it?
