Answer 1

Solution -

FSTAT Test Statistic

F = 1.5907

Below Step wise procedure to calculate Fstat-

For calculating F statistics 1st we find variance for both samples. because F Statistics is used to test Equality of two population variances.

Step-1: Let us take the hypothesis that the two sample have same variance
Null Hypothesis H0: S²₁= S²₂

Alternative Hypothesis H1 : S²₁ ≠ S²₂

For Sample A

For Sample B
