Determine the t critical value for a lower or an upper confi

Determine the t critical value for a lower or an upper confidence bound in each of the following situations. (Round your answers to three decimal places.) Confidence level = 95%, df = 5 Confidence level = 95%, df = 10 Confidence level = 99%, df = 10 Confidence level = 99%, n = 5 Confidence level = 98%, df = 22 Confidence level = 99%, n = 34 You may need to use the appropriate table in the Appendix of Tables to answer this question.

Solution

I.
The Value of alpha when d.f = 5 is 2.571

II.
The Value of alpha when d.f = 10 is 2.228

III.
The Value of alpha when d.f = 10 is 3.161

IV.
The Value of alpha when d.f = 5 is 4.032

V.
The Value of alpha when d.f = 22 is 2.508

VI.
The Value of alpha when d.f = 34 is 2.728
