Omitted variable bias: a. exists if the omitted variable is correlated with the included regressor but is not a determinant of the dependent variable. b. exists if the omitted variable is correlated
Omitted variable bias:a. exists if the omitted variable is correlated with the included regressor but is not a determinant of the dependent variable.b. exists if the omitted variable is correlated with the included regressor and is a determinant of the dependent variable.c. will always be present as long as the regression R2 < 1.d. is always there but is negligible in almost all economic examples.

Anita is running to the right with a speed of 6 m/s
Anita is running to the right with a speed of \(6.0 \mathrm{~m} / \mathrm{s}\), as shown in the figure. Balls 1 and 2 are thrown toward her by her friends (standing still on the ground). As measured by Anita, both balls are approaching her at a speed of \(11 \mathrm{~m} / \mathrm{s}\).You may assume all the motions are completely horizontal.a) According to her friends, what is the magnitude and direction of the velocity of ball \(1\left(\vec{v}_{1}\right) ?\)b) According to her...

A two-variable model involving one quantitative explanatory variable and one categorical (binary) explanatory variable (and no interaction), results in two regression lines that are: A.     Always parallel. B.     Could be parallel but, depending on the data, may not. C.      Never parallel. D.     Always horizontal. The two methods of including a binary categorical variable in a regression model are to use indicator coding or effect coding. For indicator coding in the two-variable model (with no interaction): A.     The binary variable is coded (-1,1) and the coefficient...

In the 145 years of the running of the Kentucky Derby, the overall average speed of the horses under all track conditions has been 35.9025mph. Only nine years have been run under sloppy track conditions, including the last two years. Sloppy track conditions occur when the track is saturated with water with standing water visible. The speeds (mph) of the horses in these nine years were: 36.31, 36.23, 36.62, 36.16, 36.69, 36.27, 36.41, 35.89, and 35.27. Find the Geometric mean...

The tub of a washer is in a spin-dry cycle, running at a constant angular speed of 77 rad/s for a duration of 10s. After 10s, the lid is opened and the safety switch turns off the washer. The tub slows down to rest in 5s. Find the total angular displacement (for entire 15s) in (a) radians = (b) revolutions =
