In the least-squares line ŷ = 5 − 7x, what is the value of the slope?
We have given,
ŷ = 5 − 7x
compare this equation with
m=slope
b=y intercept
slope = -7.................................................................................................................for given linear regression equation
y intercept = 5
In the least-squares line ŷ = 5 − 7x, what is the value of the slope?
We use the form ŷ = a + bx for the least-squares line. In some computer printouts, the least-squares equation is not given directly. Instead, the value of the constant a is given, and the coefficient b of the explanatory or predictor variable is displayed. Sometimes a is referred to as the constant, and sometimes as the intercept. Data from a report showed the following relationship between elevation (in thousands of feet) and average number of frost-free days per year...
A hypothesis test for the slope of the least squares regression line produces a P-value of 0.018. Which of the following conclusions is appropriate? There is insufficient evidence at the a = 0.05 level of a linear relationship between the variables. There is insufficient evidence at the a = 0.10 level of a linear relationship between the variables. There is sufficient evidence at the a = 0.01 level of a linear relationship between the variables. There is insufficient evidence at...

Objective 2: Interpret the Slope and the y-Intercept of the Least-Squares Regression Line 4.2 Least-Squares Regression 4.2.13 0 of 1 Point Question Help A student at a junior college conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, x, and grade-point average, y. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is y0.0575x +...
