Answer:
The regression line is not a good model because there is a pattern in the residual plot.
Step-by-step explanation:
Given is a residual plot for a data set
The residual plot shows scatter plot of x and y
The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.
Hence the regression line cannot be a good model as they do not approach 0.
Also there is not a pattern of linear trend.
D) The regression line is not a good model because there is a pattern in the residual plot.
Answer:
undefined
Step-by-step explanation:
since both points have a y value of ten the line is vertical, making the line undefined and therefore having no slope.
Well (1.57- 0.6 X 0.6) x 0.3 = 0.363
Answer:
x=4 is vertical line it's an undefined slope
