Answer 1

7.

(a) The test of hypothesis is about a population variance. The null hypothesis is given by
Ho
and alternative hypothesis is given by
H1
.

Но : оf — о 0

(two-sided hypothesis)

H1 o

(b) There are two critical regions such as:

Reject Ho Reject Ho

(c) Critical test statistics :

23.45 F = 15.55

1.5080

p- value = 0.21779

(d) Since the p- value is less than 0.5. The null hypothesis is not significant that is, the population variances are not equal.
