if you use a 010 level of significance in a twotail hypothes

if you use a 0.10 level of significance in a (two-tail) hypothesis test, what will you decide if Zstat = +2.02?

Solution

Given a=0.1, the critical values are Z(0.05) = -1.645 or 1.645 (from starndard normal table)

The rejection regions are if Z<-1.645 or Z>1.645, we reject the null hypothesis.

Since Z=2.02 is larger than 1.645, we reject the null hypothesis.
