Answer:
They would be perpendicular because the lines intersect at a ninety degree angle. Hope this helps! Please mark brainliest!
Step-by-step explanation:
I must assume you mean:
[(x^2 - 4) / (x - 8)] / [x - 2] -----> express this way:
[(x^2 - 4)] / [(x - 8)(x - 2)]
But x^2 - 4 = x^2 - 2^2, which is a difference of squares: a^2 - b^2 = (a + b)(a - b) ----->
[(x + 2)(x - 2)] / [(x - 8)(x - 2)] -----> (x - 2) gets cancelled out ----->
(x + 2) / (x - 8)

Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
What you do is look at the graph and whatever that line is on then that will be your answer.
