Chapter 10, Problem 68RE
Solution

To determine how the randomizations is done in the experiment.

The randomization is done by assigning the cloths to two different groups at random.

The cloths are numbered from 1 to 20 and using graphing calculator command, 10 random numbers are generated to select cloths for one of the groups. Remaining are placed in the another group.

Given information:

A company wants to test the effectiveness of a new additive for the detergent.

20 identical cloths with dirt and stains are considered.

Explanation:

An Experiment is a study of cause-and-effect between the variables.

20 cloths should be considered in two groups.

Randomization:

Students are assigned to different groups randomly.

Randomization is done in following steps:

Step 1: The volunteers are numbered form 1 to 20.

Step 2: Using the graphing calculator command randInt(1,20,10)

Step 3: 10 distinct numbers are generated and are considered in group 1

Step 4: Remaining 10 are placed in group 2
