Answer:
Explanation:
Here,

a) Test Statistic

b) Critical value for

degrees of freedom is

d.f =(5 - 1, 5 - 1)
d.f = (4, 4)
Fcritical=

Fcritical = 4.11
Critical value = 4.11
Here,
F test Statistic < critical value
so we fail to reject null hypothesis H₀
Conclusion
There is insufficient evidence to conclude the standard deviations are different.
we may assume they are equal.
