Asample of 60 items from population 1 has a sample variance of 8 while a sample of 40 items from population 2 has a sample variance of 10. if we test whether the variances of the two populations are equal, the test statistic will have a value of

a. 0.8

b. 1.56

c. 1.5

d. 1.25

 a. 0.8

Step-by-step explanation:

When we test whether the variances of the two populations are equal we use F- test.

Test statistic :

, where = sample variance from population 1.

= sample variance from population 2.

As per given , we have

and  

Then,  If we test whether the variances of the two populations are equal, the test statistic will be

Hence, the test statistic will have a value of 0.8 .

Thus , the correct answer is  a. 0.8 .

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
