You’re going to have to single out the x. So, the way to go is divide both sides by m. Then you’re left with
x = y/m
Answer:
The statement provided is TRUE.
Step-by-step explanation:
The four principle assumptions of the simple linear regression model are,
- The linearity of the relationship between the dependent variable and the independent variable. That is, value of <em>y, </em>the dependent variable for each value of <em>x</em> the independent variable is, .
- Normality of the error distribution. That is, . Thus, the variance of random error e is .
- Statistical independence of the errors or specifically no correlation between consecutive errors. That is, if , it implies that.
- Homoscedasticity of the errors, i.e. constant variance.
The first assumption clearly indicates that the <em>y</em>-values are statistically dependent upon the <em>x</em>-values.
Thus, the statement provided is TRUE.
Answer: choice3) 25
Step-by-step explanation:
The constant ratio of y/x is 2.5
so if the x value is 10 the y value would be 25(10*2.5).
