Question

It’s spring and gardening season is upon us! The manufacturer of fertilizer 1 is trying to make the claim that his product is significantly better than fertilizer 2 when it comes to plant growth. He conducted a between subjects experiment using his company’s fertilizer (1) and his competitior’s fertilizer (2) to demonstrate that his product leads to significantly higher plant growth. (See results of SPSS output above) Based on the results of this experiment, is he able to make the claim that his company’s product (Fertilizer 1) leads to significantly higher plant growth than his competitor’s product (Fertilizer 2)? The manufacturer of Fertilizer 1 is planning to replicate the experiment. Considering you’re all newly-minted statisticians capable of giving advice on research design, what recommendations do you have for him based on the outcome of the first experiment? (Utilize the concept of means, effect sizes, and p-values in your response)
