A multiple regression model using 200 data points (with three independent variables) has how many degrees of freedom for testing
1 answer:
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

Rule: Subtract 2 from the input value
Step-by-step explanation:
Examine the pattern of the input and the corresponding output for the two given ordered pairs:
Input -2 → Output -4
Output - Input = -4 - (-2) = -2
Input 1 → Output -1
Output - Input = -1 - 1 = -2
Therefore to get the output value (y-value), we subtract 2 from the input value (x-value).
As the rule for the function is the subtract 2 from the input value to get the output value, we can write this as:
Output = Input - 2
or as an equation:
Answer:
The inequality describing the situation is:
Step-by-step explanation:
Joe works as a busboy at the rate of = $7 per hour
Let the number of hours he works as a bus boy this month be = hours
∴ Amount Joe would make this month working as a busboy =
Joe works as a theater usher at the rate of = $9 per hour
Let the number of hours he works as a theater usher this month be = hours
∴ Amount Joe would make this month working as a theater usher =
Total amount Joe would make this month =
His goal is earn more than $1500 this month.
∴ The situation can be represented in the following inequality:
