For each of the following rejectionregions, sketch the sampling distribution for z and indicate the location of the rejectionregion, and determine the probability that a Type I error will be made. (Question has 9 more parts)

a.z<1.96orz>1.96

b.z<1.28

c.z<1.645orz>1.645

d.z>2.33

e.z<2.575

f. Z > 1.645

First part: b. Which sketch below shows the sampling distribution for the rejection region z less than minus 1.28?
