Answer #1

H0: Null Hypothesis: P 0.80 (Doctors believe that a surgical procedure is successful at least 80%of the time)

HA: Alternative Hypothesis: P < 0.80 (Doctors believe that a surgical procedure is successful less than 80%of the time)

Type I error: Rejection of a true null hypothesis.

So,

the Type I error in this scenario is as follows:

Suppose in reality a surgical procedure is successful at least 80%of the time. But, Doctors wrongly believe that a surgical procedure is successful less than 80%of the time. Type I error is committed in this situation.

An airline wants to test the null hypothesis that at least 60% of their customers like the selection of online snacks.

A manufacturing firm need to test the null hypothesis H0 that the probability p of a defective item is 0.1 or less, against the alternative hypothesis H1:p>0.1. The procedure is to select two items at random. If both are defective, H0 is rejected; otherwise, a third item is selected. If the third item is defective, H0 is rejected. In all other cases, H0 is accepted. What is the power of the test in terms of p?
