Answer:

The standard error of the proportion is 0.112.

Step-by-step explanation:

The standard error of a proportion is given by the following formula:

S = \sqrt{\frac{p(1-p)}{n}}

In which p is the probability of a success and n is the length of the sample.

In this problem

A success is a student defining themselves regular dietary supplement users. Our of 3000 students, 1500 do. So p = \frac{1500}{3000} = 0.5.

We take a sample of 20 of them, so n = 20.

So

S = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.5*0.5}{20}} = 0.112

0.666 is 2/3
2/3 + 9/3 = 11/3
So 3.666 as a fraction is 11/3.
As a mixed number, it is 3 and 2/3.

31. There are C(5, 2) = 10 ways to choose 2 colors from a group of 10 colors if you don't care about the order. (Here, we treat blue background with violet letters as being indistinguishable from violet background with blue letters.)

Only one of those 10 pairs is "B and V", so the probability is 1/10.
   a) P(B and V) = 10%


32. The 12 inch dimension on the figure is 0 inches for the cross section. The remaining dimensions of the cross section are 
   c) 5 in. × 4 in.


_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5!/(2!·3!) = 5·4/(2·1) = 10
