9. An experiment was performed on a certain metal to determine if the strength is a function of heating time (hours). Results based on 20 metal sheets are given below. Use the simple linear regression model. ∑X = 40 ∑X2 = 200 ∑Y = 80 ∑Y2 = 1120 ∑XY = 388 Find the estimated y intercept and slope. Write the equation of the least squares regression line and explain the coefficients. Estimate Y when X is equal to 5 hours....

A manager uses regression to express sales as a function of advertising expenditures (X1), and per capita income (X2) in your sales area. The following multiple linear regression equation is developed: Y = 10 + .51X1 + .45X2 The coefficient of determination is .96 This coefficient of determination explains that: A) 96% of sales variations are explained by the equation B) The dependent variable is not related to advertising expenditures and per capita income C) 96% of sales variations are...

Which of the following statements is false about the coefficient of determination r2
Which of the following statements are not correct? The
coefficient of determination, denoted by r^2 is interpreted as the
proportion of observed y variation that cannot be explained by the
simple linear regression model. The higher the value of the
coefficient of determination, the more successful is the simple
linear regression model in explaining y variation. If the
coefficient of determination is small, an analyst will usually want
to search for an alternative model (either a nonlinear model or a...

1a) Let's say that you made a scatterplot for bivariant data such that the x-values ranged from 50 to 85. From this, you successfully created a linear regression equation. Why should you not use the equation to make predictions of the y-value with x = 20 but you can for x = 60? b) Let the coefficient of determination be 0.81. If you were provided no additional information, what is one thing you can determine about the correlation coefficient and...
