QUESTION 7

A company that manufactures electronic components wants to evaluate the following hypothesis test, using a level of significance of 0.1.

A random sample of 12 components was taken; 6 were tested at 80° F (X₁), and 6 were tested at 120° F (X₂). The results are given below.

837 , 770, S₁ =40, S₂ =30

*The resulting test statistic has t distribution with 9 degree of freedom*

Compute the lower bound of the confidence interval that is relevant to this problem.
