A random sample of 80 employees at a large grocery store with multiple locations was asked if they spend more than 30 minutes commuting to work. Assume the true proportion of employees that spend more than 30 minutes commuting to work 35%, which of the following is closest to the probability that more than 30 employees in a sample of 80 employees would respond that they spend more than 30 minutes commuting to work each day?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
