The statistical goal of multiple regression analysis is to build a linear equation model that identifies the optimal weighted linear combination of independent variables in the study in order to optimally predict the reference variable.
Regression analysis is usually performed for one of two purposes. Predicting the value of the dependent variable of a person whose information about the explanatory variable is available, or estimating the effect of the explanatory variable on the dependent variable.
In multiple regression analysis, researchers can determine the strength of the relationship between the outcome (dependent variable) and multiple predictors, and the importance of each predictor in the relationship, often the effect of other predictors. It can be evaluated by statistically eliminating it.

Answer:
72
Step-by-step explanation:
1 out of 10 do not recommend naps, so 9 times as many do recommend naps.
9 × (8 doctors) = 72 doctors . . . . . recommend naps
Answer:
x = 5/2 or 2.5
step-by-step explanation:
2x^2 - 6x + 5 = 0
4x - 6x + 5 = 0
-2x + 5 = 0
-5 -5
-2x = -5
/-2 /-2
x = 5/2 or 2.5
Answer:
The opposite sides are always parallel.
