Carrie wants to conduct a randomized experiment on 50 articles of her dirty clothing to see if detergent A or detergent B cleans
better. Which of the following best describes the method for randomization using slips of paper within this experiment? A. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 slips of paper to wash with detergent A and the remaining slips to wash with detergent B.
B. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 of them. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
C. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Carefully place the slips of paper in a stack and choose the top 25 slips of paper. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
D. Label each article of clothing with a number from 1 to 50, and write those numbers on different-sized slips of paper. Use large slips for pants, medium-sized slips for shirts, and small slips for shorts. Shuffle the slips of paper and choose 25 slips of paper. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
E. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 of them. The numbers on those slips will represent the items that will be washed with detergent A. Replace those slips and shuffle all 50 slips again and choose 25 slips again. The numbers on those slips will represent the items that will be washed with detergent B.
