A particular brand of dishwasher soap is sold in three sizes: 30 oz, 35 oz, and 60 oz. Twenty percent of all purchasers select a 30-oz box, 50% select a 35-oz box, and the remaining 30% choose a 60-oz box. Let X1 and X2 denote the package sizes selected by two independently selected purchasers. (a) Determine the sampling distribution of
X.
x 3032.5354547.560
p(x)
Calculate E(X).
E(X) =
Compare E(X)to μ:
E(X) > μ
E(X) < μ
E(X) = μ
(b) Determine the sampling distribution of the sample variance S2.
s2012.5312.5450
p(s2)
Calculate E(S2).
E(S2) =
Compare E(S2) to σ2.
E(S2) > σ2
E(S2) = σ2
E(S2) < σ2

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?
