The computer operations department has a business objective of reducing the amount of time to fully update each subscriber’s set of messages in a special secure email system. A team designed a factorial experiment involving two factors, i.e., Interface and Media, with the goal of understanding the importance of these factors in explaining the variability in Update Time. The factor Interface has three levels, i.e., System I, System II, and System III, while the factor Media has two levels, i.e., Cable and Fiber. Consequently, there are 3x2=6 different factor-level combinations. Subscribers were randomly assigned to one of the 6 factor-level combinations and Update Time was recorded for each observation.

1. Analyze the experimental data. Report the ANOVA Table and comment on the importance of the two factors and their interaction in explaining the variability in Update Time.

2. If there are model terms with p-values > 0.05, drop them from the model and re-analyze the data under your reduced model. Refer to this as your final model.

3. Report and interpret the coefficient of determination, ? , for your final model.

4. What level(s) of the important factor(s) appears to produce the shortest Update Time?

a.      Calculate the three-firm concentration ratio for the prepared baby-food industry between 2000 and 2008.

b.     Calculate the Herfindahl-Hirschman Index (HHI) for this industry between 2000 and 2008.

c.     Did this industry become more or less concentrated between 2000 and 2008? Explain.

d.     Explain the impact of a merger on market concentration.

Why should you not invest in actively managed U.S. equity funds? Give two strong theoretical reasons (one assuming that the market is efficient and one that it is not) and one strong empirical reason

Combustion of 0.2000 g sample of Vitamin C yields 0.2998 g CO₂ and 0.0819 g H₂O. What is the mass percent of each element? What is the empirical formula for Vitamin C?

when 4.027 grams hydrocarbon, CxHy, we're burned in a combustion analysis apparatus, 12.64 grams of CO2 and 5.174 grams H2O we're produced.

I need empirical and molecular formulas

An unknown compound contains only C,H and O. Combustion of 5.80 g of this compound produced 14.2 g of CO2 and 5.80 g of H2O. What is the empirical formula of the unknown compound?
