Your company is evaluating two cloud-based secured data storage services. "Great Sky," the newer service, claims its uploading and downloading speeds are faster than the older service, "Clear and Steady Skies." You need to make a decision based on published access times for both services at different times and for varying file sizes. To make your decision, you purchase two statistical studies from which you discover the average download time for Great Sky is 0.67 sec. per MB and for Clear Steady Skies is 0.84. Additionally, the studies indicate the following sample information: NGS = 60 ncss = 50, SGS = 0.25 and scss = 0.55. Use a .05, and the five step hypothesis testing procedure to make the appropriate decision. Prepare an Excel worksheet properly labeled and well formatted to share with your boss (a very picky person that truly appreciates good looking work product).

State the two-way ANOVA identity for degrees of freedom and interpret its meaning with regard to partitioning the total degrees of freedom in the data.
