N1=26 n2=13
Mean1=48 mean2=45
Standard deviation1=9,2 Standard deviation2=4,1
Construct a 95% confidence interval for the two population variance and interprete your answer
Expert Solution
Step 1
The first sample size is 26, second sample size is 13, first standard deviation is 9.2, and second standard deviation is 4.1.
The confidence level is 95%.
The degrees of freedom is,
The critical value of at (25,12) degrees of freedom can be obtained using the excel formula “=F.INV.RT(0.025,25,12)”. The critical value is 3.0077.
The critical value of at (25,12) degrees of freedom can be obtained using the excel formula “=F.INV.RT(0.975,25,12)”. The critical value is 0.3976.
