Suppose a drop of dye, with a concentration of 1 unit, is dropped at latex: x=0x = 0 at latex: t=0t = 0. at latex: t=5t = 5, the variance latex: (\sigma^2)( σ 2 ) of the concentration curve is found to be 20. estimate the diffusion coefficient latex: (d)

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
