need the answer ASAP please!!!

Is there any way i can answer this on a Ti 83 plus???

ume that both samples are Test the indicated claim apoutine yanances or standard av independent simple random samples from popu Use the summary statistics below to test the claim that the sample populations with different variance Use a significance level viations of two populations.

Test Statistic :- F = 0.6498

P value = 0.2416

Reject null hypothesis if P value < α = 0.05
Since P value = 0.2416 > 0.05, hence we fail to reject the null hypothesis
Conclusion :- We Fail to Reject H0

There is insufficient evidence to support the claim that samples comes from populations with different variances.
