If the alpha level is changed from alpha level of .05 to alpha level .01):
a. What happens to the boundaries for the critical region? Explain in detail (do not just talk about size), and give examples of actual z-critical values.
b. What happens to the probability of a Type I error and why is this significant for researchers? Explain in detail (again, do not just talk about size).
Be sure to include all of the processes, formulas and steps required to arrive at the final answers
