Answer: FALSE
The vertical line is Y (rise) and the horizontal line is X (run)
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point A:
![\to df = n - 1 = 71-1= 70](https://tex.z-dn.net/?f=%5Cto%20df%20%3D%20n%20-%201%20%3D%2071-1%3D%2070)
In point B:
![\to t = \frac{(x -X)}{s} = \frac{(93-81)}{8} = \frac{12}{8}= 1.5](https://tex.z-dn.net/?f=%5Cto%20t%20%3D%20%5Cfrac%7B%28x%20-X%29%7D%7Bs%7D%20%3D%20%5Cfrac%7B%2893-81%29%7D%7B8%7D%20%3D%20%5Cfrac%7B12%7D%7B8%7D%3D%201.5)
In point C:
For df = 70, the top 5% critical t score
tcrit = 1.666914479
Thus,
![\to 1.666914479 = \frac{(x - 81)}{8}\\\\\to 1.666914479 \times 8 = (x - 81)\\\\\to 13.335315832 = (x - 81)\\\\\to 13.335315832 +81 =x \\\\\to x= 94.335315832](https://tex.z-dn.net/?f=%5Cto%201.666914479%20%3D%20%5Cfrac%7B%28x%20-%2081%29%7D%7B8%7D%5C%5C%5C%5C%5Cto%201.666914479%20%5Ctimes%208%20%3D%20%28x%20-%2081%29%5C%5C%5C%5C%5Cto%20%2013.335315832%20%3D%20%28x%20-%2081%29%5C%5C%5C%5C%5Cto%20%2013.335315832%20%2B81%20%3Dx%20%5C%5C%5C%5C%5Cto%20x%3D%2094.335315832)
In point D:
For df = 70, the top 5% critical t score
tcrit = -1.666914479
![\to -1.666914479 = \frac{(x - 81)}{8}\\\\\to -1.666914479 \times 8= (x - 81)\\\\\to -13.335315832= (x - 81)\\\\\to -13.335315832+81 = x \\\\\to x = 67.664684168\\\\](https://tex.z-dn.net/?f=%5Cto%20-1.666914479%20%3D%20%5Cfrac%7B%28x%20-%2081%29%7D%7B8%7D%5C%5C%5C%5C%5Cto%20-1.666914479%20%5Ctimes%208%3D%20%28x%20-%2081%29%5C%5C%5C%5C%5Cto%20-13.335315832%3D%20%28x%20-%2081%29%5C%5C%5C%5C%5Cto%20-13.335315832%2B81%20%3D%20x%20%5C%5C%5C%5C%5Cto%20x%20%3D%2067.664684168%5C%5C%5C%5C)
In point E:
The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is

We will plug in x = 24, and y = 6:
All is wrong except:
6 = 1/4 · 24
Answer:<span> D ) y = 1/4 x</span>
