An article describes an experiment to determine the effectiveness of mushroom compost in removing petroleum contaminants from soil. Out of 155 seeds planted in soil containing 3% mushroom compost by weight, 74 germinated. Out of 155 seeds planted in soil containing 5% mushroom compost by weight, 86 germinated. Can you conclude that the proportion of seeds that germinate differs with the percent of mushroom compost in the soil? Find the P-value and state a conclusion.

Expert Solution

Let denote the proportions of seeds that germinate among seeds planted in soil containing 3% and 5% mushroom compost by weight respectively.

Conclusion : There is insufficient evidence to conclude that the proportion of seeds that germinate differs with the percent of mushroom compost in the soil.
