e) if the hypothesis is tested at the 1% level of significance instead of 5%, how will this affect the power of the test?
f) the engineers hoped to base their decision on the reactions of 50 drivers, but time and budget constraints may force them to cut back to 20. how would this affect the power of the test? explain."
