A sample of 50 observations is selected from a normal population. The sample mean is 31, and the population standard deviation is 3. Conduct the following test of hypothesis using the 0.05 significance level.

H₀: 30

H₁: > 30

a.	Is this a one- or two-tailed test?
	"One-tailed"-the alternate hypothesis is greater than direction. "Two-tailed"-the alternate hypothesis is different from direction.

b.	What is the decision rule?(Round your answer to 3 decimal places.)
