0.01 level of significance, test the manager's claim.

Question 6
From the problem about testing the claim that production is not out of control that when defects exceed 3%.

Question 7
From the problem about testing the claim that production is not out of control that when defects exceed 3%.
Draw the conclusion. Interpret the results.
Check all that apply.
There is not enough evidence to conclude that the defects exceed 3%
This might be a sample fluctuation and production is not really out of control.
There is a significant evidence to conclude that null hypothesis is true
