Answer:ok
Step-by-step explanation:
Answer:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96 .
Option B is the correct answer.
Step-by-step explanation:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96.
Option B is correct because after subtracting it from 1, it will become a standardized test if the slope is equal to 0 or not.
Answer:
First question: Choice A
second question:Choice D
Third question: Choice c
Fourth question: Choise b
5th Question: choice b
First find slope
(-2-6)/(9-5) = -8/4 = -2
Y = -2x + b
6 = -2(5) + b, b = 16
Solution: D
5x - 7y =58
y =-x +2
Using the substitution method, replace y in the first equation with the second equation:
5x - 7(-x+2) = 58
Simplify by using the distribution property:
5x - (-7x) - 14 = 58
Simplify by combining like terms:
12x -14 = 58
Add 14 from each side of the equation:
12x = 72
Divide both sides by 12:
X = 72/12
x = 6
Now you have x, replace x in the second equation and solve for y:
y = -x +2
y = -6 +2
y = -4
X = 6, y = -4
