EMC Proven Professional – Data Science and Big Data Analytics — Question 28

You are testing two new weight-gain formulas for puppies. The test gives the results:

Control group: 1% weight gain -

Formula A. 3% weight gain -

Formula B. 4% weight gain -
A one-way ANOVA returns a p-value = 0.027
What can you conclude?

Answer options

• A. Either Formula A or Formula B is effective at promoting weight gain.
• B. Formula B is more effective at promoting weight gain than Formula A.
• C. Formula A and Formula B are both effective at promoting weight gain.
• D. Formula A and Formula B are about equally effective at promoting weight gain.

Correct answer: A

Explanation

The p-value of 0.027 indicates that there is a statistically significant difference in weight gain among the groups, meaning at least one formula (either A or B) is effective. However, it does not specifically identify which formula is superior or if both are effective, making option A the correct conclusion.
