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.

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.

p(s2)
Calculate E(S2).
E(S2) =
Compare E(S2) to σ2.
E(S2) > σ2
E(S2) = σ2
E(S2) < σ2

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
