Explanation / Answer

5) Test statistic is 1.99

Level of significance = 0.05

Critical value = 1.96

Test statistic > critical value we reject null hypothesis.

Correct option is Reject H0

6) n1 = 16 , n2 = 26 , alpha = 0.05

For test two variance we use F test statistic.

Degrees of freedom = n1 - 1 , n2 - 1 = > 16 - 1 , 26 - 1 = > 15 , 25

Critical value = 2.089 Using f table.
