Question

You are to investigate the following claim: “Laundry detergent containing bleach gives a 15% better result for all fabrics and colors than detergent without bleach.” (a) Briefly describe an experimental setup for testing the hypothesis. In particular, describe how you would implement blinding and randomization in the experiment, and explain what these are good for.

Answer 1

In this research, we shall use the experimental model of the research, this model test hypothesis according to the result of the experiment.

To collect the appropriate data, we shall conduct an experiment in which, two groups shall be randomly selected and one group shall use the laundry detergent without bleach while another group shall use detergent with bleach.

The result of the first group shall be considered as the primary group and resulted examined according to the hypothesis while the second group will show a different result.

Mean testing and two factors analysis will examine the research result to test the given hypothesis. If we get null hypothesis correct, the result would be in favor of the primary group and could be implemented according to the hypothetical statement.
