Consider a simple regression in which the dependent variable mim ¼ mean income of males who are 18 years of age or older, in thousands of dollars. the explanatory variable pmhs ¼ percent of males 18 or older who are high school graduates. the data consist of 51 observations on the 50 states plus the district of columbia. thus mim andpmhs are ‘‘state averages.’’ the estimated regression, along with standard errors and t-statistics, is

the square root of what number? if you add that, then someone will probably answer the question.

7.3

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
