Answer: 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 .
the answer is 869. hope you pass!
1st Step:We should first change them all to have a common denominator.
2nd Step:We should find the least common multiple
