It is found that Margo will be using random sampling.
• Random sampling in statistics is a part of the sampling technique in which each sample has an equal probability of being chosen. In other words, a sample chosen randomly is an unbiased representation of the total population.
Sample strategies may be classified as :
1) Convenient : The sample which is drawn from a conveniently available pool.
2) Random : When all options are into a hat and draw some of team
3) Systematic : Every kth element
4) Cluster : When we divide population into groups called clusters, and each element os cluster is surveyed.
5) Stratified : In stratified also divides the population into groups, However only some of the elements of the group are surveyed.
According to the question
Marbles are taken from the bag, and after they are taken they are again placed back in the bag so it depicts Random Sampling.

Answer:
1.) 40 mph
2.) $160 per month
3.) 2 goals per game
4.) $0.20 per ounce
5.) 1/4 mile or 0.25 mile per minute
6.) 8 tickets per minute
7.) $1.25 per Euro
8.) 25 miles per hour
9.) 2 flies per minute
10.) 3 problems per minute
11.) 15 barks per minute and 900 barks per hour
12.) 2 pages per minute
13.) 12/11 patients per hour
14.) $5 per car
15.) 7 cars per minute
16.) $2.50 per soft drink
17.) 3/4 points or 0.75 points per minute
18.) 8.5 minutes per mile
19.) 25 cents per ounce
20.) $9 per hour
Step-by-step explanation:
1.) 160/4 = 40
2.) 480/3 = 160
3.) 8/4 = 2
4.) 2.80/14 = .20
5.) 5/20 = 1/4 or .25
6.) 96/12 = 8
7.) 25/20 = 5/4 or 1.25
8.) 375/15 = 25
9.) 8/4 = 2
10.) 24/8 = 3
11.) 30/2 = 15
There are 60 minutes in an hour, so 15 x 60 = 900
12.) 40/20 = 2
13.) 6 / (11/2)
You'll want to turn 11/2 hours into one hour, so multiply 11/2 by its reciprocal, which is 2/11. Multiply 6 by 2/11 as well.
(12/11) patients per hour
14.) 25/5 = 5
15.) 35/5 = 7
16.) 12.50/5 = 2.50
17.) 9/12 = 3/4 or .75
18.) 34/4 = 17/2 or 8.5
19.) 4/16 = 1/4 or $0.25 which is 25 cents
20.) 36/4 = 9
