Question

"a company manager found the number of vacation days available in the number of vacation days taken during one year for a sample of employees the equation of the regression line is y=0.8x - 0.47.

Complete the table above and state the residual value(e) to the nearest hundedth"

Answer 1

The equation of the regression line is y = 0.8x - 0.47. To complete the table, substitute the x values into the equation. The residual value is the difference between the observed and predicted values.

Step-by-step explanation:

The equation of the regression line is y = 0.8x - 0.47. To complete the table, you need to substitute the given values of x into the equation to find the corresponding values of y. For example, if x = 5, then y = 0.8(5) - 0.47 = 3.53.

Similarly, you can substitute the other x values to find the corresponding y values.

The residual value (e) represents the difference between the observed y value and the predicted y value on the regression line. To find the residual value, subtract the predicted y value from the observed y value.

For example, if the observed y value is 6.2 and the predicted y value is 5.9, then the residual value is 6.2 - 5.9 = 0.3.
