Given sample size of 34, with sample mean 660.3 as well as sample standard deviation 104.9, we perform the following hypothesis test.
Null Hypothesis 0:700H?=
Alternative Hypothesis :700aH??
1. What are the border values (in terms ofx) between acceptance and rejection of this hypothesis?
2. What is the power of this test if the assumed true mean were 690 instead of 700?
