In order to test for the significance of a regression model involving 5 independent variables and 123 observations, the numerato
allochka39001 [22]

Answer: The numerator and denominator degrees of freedom (respectively) for the critical value of F are <u>4</u> and<u> 118 .</u>

Step-by-step explanation:

We know that , for critical value of F, degrees of freedom for numerator = k-1

and for denominator = n-k, where n= Total observations and k = number of independent variables.

Here, Numbers of independent variables(k) = 5

Total observations (n)= 123

So, Degrees of freedom for numerator  = 5-1=4

Degrees of freedom for denominator =123-5= 118

Hence, the numerator and denominator degrees of freedom (respectively) for the critical value of F are <u>4</u> and<u> 118 .</u>

What is the slope intercept form of the equation y+5= 4(x+8)
hram777 [196]

Answer:

y=4x+27

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

y+5=4(x+8) ----> equation of the line into point slope form

Convert to slope intercept form

Isolate the variable y

Distributed left side

y+5=4x+32

subtract 5 both sides

y=4x+32-5\\ y=4x+27
