A student set up an experiment to investigate osmosis as shown. The student used visking tubing which is a partially permeable membrane. The student put 25 cm of 20% sucrose solution into visking tube 1 and 25

cm of distilled water into visking tube 2. Both tubes were placed in a 5% sucrose solution and left for 1 hour.

Explain how and why tube 1 and tube 2 would look different after one hour.

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). =
