I need ur help with the following problem:
We have created a 90% confidence interval for � with the result (9, 14).
9 < u < 14
---------------------
What conclusion will we make if we test
Ho : � = 19 verses
Ha : � # 19
at α = 0.10?
-------------------------
Comment:: You must have a sample mean somewhere in your problem.
Does the sample mean fall in the 90% confidence interval??
If it does, you accept Ho ; if it does not, you reject Ho.
