Explain your results with in-depth analysis. See the attached excel file for data. There are two sheets with fuel cost and strength.

1. For the first sample, analyze the fuel cost for a business.

H0: σ ≤ 300

Ha: σ > 300

We shall choose α=0.05

Will you accept or reject the hypotheses? Explain.

2. For the second sample, analyze the strength between individuals.

H0: σ ≤ 10

Ha: σ> 10

We shall choose α=0.05

Will you accept or reject the hypotheses? Explain.

Need explanations, charts and graphs where necessary. Provide peer-reviewed citations.
