The test statistic of zequalsnegative 2.30 is obtained when testing the claim that pequals1 divided by 6. a. Using a significance level of alphaequals0.10, find the critical value(s). b. Should we reject Upper H 0 or should we fail to reject Upper H 0?
Homework Answers
We have given,
Z test statistic =-2.30
Consider, two tailed test.
a) Z critical values are 
.........by using Z table or Excel =NORMSINV(1-(0.1/2)) and
=NORMSINV((0.1/2))
b) | Z test statistic | > 1.645
Therefore, we reject H0 at
