Question

Suppose that participants who adhere to a particular weight loss program lose an average of 1.5 lbs per week. Write a population regression model that describes how participants' mean current weight changes with time x1 (in weeks) and starting weight x2 (in pounds).

Answer 1

Answer:

y = x₂ - 1.5 × x₁.

Step-by-step explanation:

Regression model is a technique of analysis in which a variable known as dependent variables and another variables known as the independent variables are analyzed to determine their relationship.

So, from the question given above we have that; "Suppose that participants who adhere to a particular weight loss program lose an average of 1.5 lbs per week".

Also, we are given that time = x1 (in weeks) and weight = x2 (in pounds). Therefore the regression equation is given as below;

y = x₂ - 1.5 × x₁.
