(b) Determine the value of the confidence coefficient z(a/2) for 1-α-0.99. You may need to use the appropriate table in Appendix B to answer this question. Need Help?Read It Talk to a Tutor

Answer 1

a) The valievof confidence coefficient can be found by Z statistic table shown below, now here alpha= 18 %and alpha/2 will be 9% hence

$Z_{\frac{\alpha}{2}}=1.34$

By table.

b) Here alpha is 1% hence alpha/2= 0.5% Now by Z table Confidence coefficient

$Z_{\frac{\alpha}{2}}=2.58$
