Describe about the need of mathematical solution for least square regression line?
Researchers record the fuel consumption of a car y (in miles per gallon) at various speeds x (in miles per hour). Using software, they determine that the least-squares regression line of their data is
y^=70.243−0.329x
If the observed fuel consumption of the car was y = 49y=49 mpg while moving at a speed of x = 20x=20mph, what would be the error (i.e., residual) in the predicted fuel consumption at this speed found with the least-squares regression line?
(Do not round your answer.)
An assumption of regression analysis is homoscedasticity, which states that the
residuals exhibit no patterns across values for the dependent variable.
relationship between the independent and dependent variables is linear.
residuals exhibit no patterns across values for the independent variable.
variation of the dependent variable is the same across all values for the independent variable.

This is achieved using a linear equation that accurately models the quantitative relationship between the dependent (unknown) and independent (known) variables. In other words, by looking at how one variable affects another, this method can accurately forecast the value of the dependent variable. It involves choosing the variable to forecast and using another variable to make informed predictions about its value. In experiments, the independent variable is the cause, and its value remains constant while other variables have been modified. On the other hand, the dependent variable is the effect, and changes influence its value in the independent variable.
