Consider the following least squares specification between test scores and the student-teacher ratio: Test Score^ = 557.8 + 36.42 ln (Income). According to this equation, a 1% increase income is associated with an increase in test scores of:

Assume an omitted variable which is in the error term of a population regression model is positively correlated with one of the independent variables in the model. An estimate of a slope coefficient from a regression where the omitted variable is not included __________ the true value of slope parameter.

Suppose your population regression model has three independent variables. You want to test whether first two independent variables have any effects on the dependent variable. The test statistics is ______ and _______.

Consider the following multiple regression models A) to D) below. DFemale = 1 if the individual is a female, and is zero otherwise; DMale is a binary variable which takes on the value one if the individual is male, and is zero otherwise; DMarried is a binary variable which equals one for married individuals and is zero otherwise, and DSingle is (1-DMarried). Regressing weekly earnings (Earn) on a set of explanatory variables, you will experience perfect multicollinearity in the following cases unless:

AdventureLand theme park recently received a large number of complaints from customers who had endured delays while waiting to ride on AdventureLand’s largest roller-coaster, Monster Train. As newly appointed Operations Manager, you are considering the problem of delayed rides on Monster Train. By observing 100 delayed Monster Train rides over a ten week period, you find that a variety of factors are contributing to the Monster Train delay problem. The results of your study are summarized here: Question-3.pngThe diagram provided above in which you visually organized the problems you observed, is often called a __________.

Cars arrive at the King Burger Take Away Restaurant at an average of 2 cars per hour. The restaurant can serve an average of 10 cars per hour. Assume this situation fits the assumptions of the M/M/1 queuing model. Po = 0.8.  λis the arrival rate, and μis the service rate.  Pn=P0*λμnWhich of the following is the closest to the probability of finding exactly two cars at King Burger Take Away Restaurant?

Consider the following project network, for which task and task duration data (in weeks) are provided, as well as the early start (ES), early finish (EF), late start (LS), and late finish (LF) times.  What is the slack time associated with task “F”? Question-7.png
