DISCUSSION FILE # 16 We believe that the percentage of our company fleet cars that will pass inspection is
80%
. We decide to run a test to see if it is
80%
or if it isn't. We sample 20 cars and find that 17 will pass. What's the conclusion from our test at a
10%
alpha level? Fail to reject and conclude that
p>0.8
Inconclusive, since the experiment doesn't meet normality requirements Reject and conclude that
p<0.8
Fail to reject and conclude that
p=0.8
Accept the null and state that
p=0.8
