In the chapter preview we presented a study showing that handling money reduces the perception pain (zhou, vohs, & baumeisyer,2009).in the experiment, a group of college students was told that they were participating in a manual dexterity study. half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. after the counting task, the participants were asked to dip their hands into bowls of very hot water (122 f) and rate how uncomfortable it was. the following data show rating of pain similar to the results obtained in the study. counting money 7 8 10 6 8 5 7 12 5 counting paper 9 11 13 10 11 9 15 14 10a) is there a significant differences in reported pain between the two conditions? use a two-tailed test with a=.01.b) compute cohen's d to estimate the size of the treatment effect.

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
