Abond analyst is analyzing the interest rates for equivalent municipal bonds issued by two different states. at α = 0.05, we wish to test whether there is enough evidence to conclude that there is a difference in the interest rates paid by the two states. what is the value of the test statistic? state a state b sample size 80 50 mean interest rate (%) 4.0 4.5 population variance 0.04 0.03

15.08

Step-by-step explanation:

The test statistic for difference between two population means is given by :-

Given :                             State A   State B

Sample size                       80            50

Mean interest rate (%)        4.0           4.5

Population variance           0.04        0.03

Then , the test statistic for difference between two population means will be :-

Hence, the value of the test statistic will be 15.08 .
