9.1 If you use a 0.05 level of significance in a (two-tail)
hypothesis test, what will you decide if ZSTAT = -0.76?
9.2 If you use a 0.05 level of significance in a (two-tail)
hypothesis test, what will you decide if ZSTAT = + 2.21?
9.3 If you use a 0.10 level of significance in a (two-tail)
hypothesis test, what is your decision rule for rejecting a
null hypothesis that the population mean is 500 if you use
the Z test?
9.4 If you use a 0.01 level of significance in a (two-tail)
hypothesis test, what is your decision rule for rejecting
Ho : µ = 12.5 if you use the Z test?
9.5 What is your decision in Problem 9.4 if ZSTAT = -2.61?
9.6 What is the p-value if, in a two-tail hypothesis test,
ZSTAT = + 2.00?

test the null hypothesis at the 0.10 level of significance?
9.8 What is the p-value if, in a two-tail hypothesis test,
ZSTAT = -1.38?
