Find the critical z values. Assume that the normal distribution applies. Two-tailed test; alphaequals0.05 zequals nothing (Round to two decimal places as needed. Use a comma to separate answers as needed.)
ANSWER:
Given that . , Hence
Now for a two failed test, the critical value will be :
,
hence the answer is
