We can make a conclusion about the data collection method used was fair since both shoe designs were tested on identical parameters option (B) is correct.

<h3>What is simple random sampling?</h3>

Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.

We have:

Two manufacturers of the shoe company:

  • Fastex Shoes
  • SportsPlus

SportsPlus came up with a design that it claims performs even better than Fastex's design.

SportsPlus decided to test the claims:

  • It created two groups of 15 randomly selected athletes each.
  • Members of both groups were pretested and determined to have equal athletic ability.
  • Additionally, they followed the same nutrition plan and training program during the study.

Based on the data the statement "The data collection method used was fair since both shoe designs were tested on identical parameters".

Thus, we can make a conclusion about the data collection method used was fair since both shoe designs were tested on identical parameters option (B) is correct.
