Question 204720: a) Suppose that in a two-tail hypothesis test you compute the value of the test statistic Z as -1.38. What is the p-value?
b) In the above problem, what is your statistical decision if you test the null hypothesis at the 0.01 level of significance?

---------------
Since it is a 2-tail test the p-value
= 2*P(z<-1.38) = 0.1676
Since the p-value is greater than 1%, Fail to reject Ho.
