Question
A LR analysis produces the equation Y = -3.2X + 7. This indicates that:*1 pointA 1 unit increase in X results in a 3.2 unit decrease in Y.A 1 unit decrease in X results in a 3.2 unit decrease in Y.A 1 unit increase in X results in a 3.2 unit increase in Y.An X value of 0 would would increase Y by 7.
Solution
The correct answer is "A 1 unit increase in X results in a 3.2 unit decrease in Y."
Here's why:
The equation Y = -3.2X + 7 is a linear regression equation, which is used to predict the value of a dependent variable (Y) based on the value of an independent variable (X).
The coefficient of X in the equation is -3.2. This is the slope of the line, and it indicates how much Y changes for each unit change in X.
Since the coefficient is negative, this means that for each unit increase in X, Y decreases by 3.2 units. Conversely, for each unit decrease in X, Y increases by 3.2 units.
The constant term in the equation is 7. This is the Y-intercept, and it indicates the value of Y when X is 0. So, an X value of 0 would result in a Y value of 7. However, this does not mean that an X value of 0 would increase Y by 7. Rather, it means that when X is 0, Y is 7.
