Question 1039454
H0 : μ ≤ 10
H1 : μ > 10

A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation 3. Using the .05 significance level:

a.	State the decision rule. (Round your answer to 3 decimal places.)
The decision rule depends on the value of alpha (the significance level).
Find the value of "t" with a left tail of 0.95 and df = 9
--------------------------------------
invT(0.95,9) = 1.833
---------------------------

Reject H0 if t > 1.833 ?
