A proportional relationship can be mathematically expressed as follows for light intensity (1) in lumens when a subject is at the light source. Lumen. s at cuTeTit distandas 1 Lumens at origrn or souTCe So, if a light intensity (I) is 502 lumens at the source, what is the light intensity (I) at 6 distance from the source,?

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). =
