Calculate the periodic interest rate that matches the payment interval for each annuity (to the nearest 0.001%):

If you wish to construct 98% upper confidence bound (UCB) for the difference between population proportions, then the approximate z-value you should use is:

A) 2.33
B) 2.05
C) 1.96
D) 1.65
E) 1.41

As the alternative value of μ increases,so does the power of the test.
