Create the confidence interval for sigma^2 using the data from problem 1 with = 0:05. The endpoints of the confidence interval are:

a.The correct answer is not given here.

b. [1:3637;21:0584]

c. [1:2424;19:1799]

d. [0:7793;12:0337]

e. [0:7793;12:0337]

Data from problem 1:

1 2 3

4 5 10

b. Based on the results of the con dence interval in problem 8 what would the conclusion be for a hypothesis test with type 1 error of 0:05?

a. Fail to reject the Null hypothesis.

b. Reject the null hypothesis.

c. We cannot say the results of this hypothesis test using the C.I. from problem 8.

d. The correct answer is not written here.

e. There is not enough information to solve the problem.

c. Based on the results of the con dence interval in problem 8 what would be the conclusion for a hypothesis test with type 1 error of 0:01? Here the hypothesis test is H0 : sigma^2 = 2 vs. Ha : sigma^2 does not equal 2.

a. Fail to reject the Null hypothesis.

b. Reject the null hypothesis.

c. We cannot say the results of this hypothesis test using the C.I. from problem 8.

d. The correct answer is not written here.

e. There is not enough information to solve the problem
