Analyzing Data and Hypothesis Testing

Raising chickens in commercial chicken farms is a growing industry, as there is a shift from red meat to more white meat. New Jersey Red Chickens are a favorite chicken and the Feed is Us company has a new chicken food that they claim is excellent for increasing weight and naturally it costs more. You have heard this line before and therefore are skeptical but the potential pay off is huge. You buy a small amount and feed it to ten chickens, which you choose at random.

Chicken Weights

4.37
4.33
4.35
4.30
4.39
4.36
4.38
4.40
4.39

At the .01 level of significance is there evidence that the chicken weight exceeds the average chicken weight of 4.35 pounds.

We must analyze the data, and then write up your results. The answer must include:
? Problem Definition
? Secondary Research Article
? Hypothesis Testing
? Explain in everyday words but also have the formal steps show with results)
? Conclusion/recommendation
