Question

The cumulative probability distribution shows the probability 10 O A. of two or more events occurring at once O B. that a random vaniable less than or equal to a particular value. O c. of all possible events occurring O D. that a random variable takes on a particular value given that another event has happened 11. Analyzing the effect of minimum wage changes on teenage employment across the 48 contiguous U.S. states from 1980 to 2004 is an example of using OA. time series data. O B. cross-sectional data. O c. panel data O D. having a treatment group vs. a control group, since only teenagers receive minimum wages 12. Consider the following linear transformation of a random variable y = is the where u, is the mean of x and standard deviation. Then the expected value and the standard deviation of Y are given as O A. 0 and 1 O B. Cannot be computed because Y is not a linear function of X O C. 1 and 1 O D. and ox 13. Assume that Y is normally distributed N(u, o. Moving from the mean (u) 1.96 standard deviations to the left and 1.96 standard deviations to the right, then the area under the normal p.d.f. is O A. 0.05 O B. 0.95 O C. 0.33 O D. 0.67 14. The regression R is a measure of O A. whether or not ESS> TSS. O B. the square root of the correlation coefficient whether or not X causes Y OC. O D. the goodness of fit of your regression line.
