Question 451195: I have a multiple choice question that asks about the rejection areas. I've been trying to solve since Monday and still do not "get it"..
What are the two rejection areas in using a two-tailed test and the 0.01 level of significance?
A. Above 1.96 and below –1.96
B. Above 1.65 and below –1.65
C. Above 2.58 and below –2.58
D. Above 1.00 and below –1.00
E. None of the above
Hi,
See below for the rejection areas at various levels of confidence for larger samples
.01 then... below -2.58 and above 2.58 would be the rejection areas
a a/2 crtical regions
