In designing an experiment involving a treatment applied to 9 test subjects, researchers plan to use a simple random sample of 9 subjects selected from a pool of 27 available subjects. (recall that with a simple random sample, all samples of the same size have the same chance of being selected.) answer the questions below. a. how many different simple random samples are possible?

4686825

Step-by-step explanation:

Given : Researchers plan to use a simple random sample of 9 subjects selected from a pool of 27 available subjects.

To Find :  How many different simple random samples are possible?

Solution:

Total subjects = 27

No. of subjects should be in sample = 9

So, to find How many different simple random samples are possible?

So, we will use combination

n = 27

r = 9

Substitute the values

Hence 4686825 different simple random samples are possible

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
