Answer #1

Let's write the null hypothesis ( H0 ) and the alternative hypothesis (H1 ) from the given claim.

a) If we reject the null hypothesis which is true on the basis of sample data then Type I error is occur.

Therefore correct choice of question ( a) is C ) Type I error.

b) If we fail to reject null hypothesis which is in actual false on the basis of sample data then Type II error occur.

Therefore correct choice of question ( b) is C ) Type II error.

c) Here we reject null hypothesis and so we accept the alternative hypothesis. So we find the correct decision from the sample data.

So correct choice of ( c ) is A ) Correct Decision.

d) Here the result of the sampling does not lead to the conclusion that the mean cost to community hospitals per patient per day in Ohio exceeds the national mean. So we fail to reject the true null hypothesis. So there is no error in the decision.

SO correct choice is B) Correct decision.
