Answer:
196
Step-by-step explanation:
Formula of degree of freedom for simple regression = n-2
Formula of degree of freedom for multiple regression = n-k-1
We are given the case of multiple regression and there are three independent variables.
So, k = 3
n = 200
So, Degree of freedom for multiple regression =
= 
= 
So, Option A is true .
Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
0.21 is less than half because a half is 0.5.
So 0.21 is less than 0.5 because the tenths place is less than 5 which makes 0.21 smaller than a half
Answer:
rise = -3; run = 1
or
rise = 3; run = -1
Step-by-step explanation:
The equation is
y = -3x + 1
The equation is in the slope-intercept form,
y = mx + b
m = -3
The slope is -3.
slope = rise/run = -3
We need to write -3 as a fraction to see the rise and the run.
-3 = -3/1 = 3/-1
rise/run = -3/1
rise/run = 3/-1
You can have a rise of -3 and a run of 1, or you can have a rise of 3 and a run of -1. They are both correct.
Answer:
k=1/4
Step-by-step explanation:
1/4x1=1/4
0x1/4=0
-1x1/4=-1/4
-2x1/4=-1/2
Very easy
