Answer:
C. 5,166
Step-by-step explanation:
because of the word product, it means multiplication
Answer:
Step-by-step explanation:
n = sample size = 5
a) Let us determine the sum
Now we can determine
The estimate b of the slope β is the ratio of and
The mean is the sum of all value divide by number of values
The estimate a of the intercept is
General least square equation;
replace alpha by a = 3 and beta by b = 0.67 in general least equation
y = a + bx
195.9 + 0.67x
b)
<em>Scatter plot is shown in the attached file</em>
x is on the horizontal axis
y is n the vertical axis
The degree of freedom of regression is 1
because we use one variable s predictor variable
The degree of freedom of error is the sample size n decrease by 2
Total df is equal to the sum of seperate degree of freedom dfR and dfE
total df = 1 +3 4
Total SS =Syy= 45007.2
SSE + Total SS = SSR
= 45007.2 - 43146.9296
= 1860.2705
Answer:
Yes it is linear
Step-by-step explanation:
A linear equation has the following form:
y = mx + b
where
m is the slope
b is the y-intercept.
You can also perform a vertical line test. If the line touches your graphed function in more than one spot, it is not a function.
The picture attached is the result when graphed.
