Consider the following regression equation for the US (Standard errors in parentheses):Pt=4.00-.01PRPt + .03PRBt + .20YDt(.005) (.02) (.04)Rbar2=.98 n=29where pt= per capita pounds of pork consumed in time period tPRPt =the price of pork in time period tPRBt =the price of beef in time period tYDt =per capita disposable income in time period ta. Hypothesize signs and specify the appropriate null and alt. hypotheses for the coefficients of each of these variables (one sided test)b. Test your hypotheses using the t-test at a 5% level of significance

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp

Jennifer graphs the function f(x)=x squared. then she graphs the function f(x-3). how does the graph f(x-3) differ from the graph of f(x)
