Discuss the issues of statistical significance and practical importance in each scenario. A process for producing I-beams of oriented strand board used as main support beams in new houses has a mean breaking strength of 2,000 pounds/feet. A sample of boards from a new process has a mean breaking strength of 2,150 pounds/feet. The improvement is statistically significant, but the per-unit cost is higher. In what scenario would this matter, if any? Under continuous use, the mean battery life in a certain cell phone is 45 hours. In tests of a new type of battery, the sample mean battery life is 46 hours. The improvement is statistically significant, but the new battery cost more to produce. When this improvement make sense and at what price?

Design a Grid-Connected PV system to provide 50% of the power to a residential facility that uses 9,000 kWh per year. 1. Calculate how much kWh the Grid-Connected PV system should produce per year. 2. Calculate the annual power generated in kWh per year from 1kW module, assuming a 1 kW PV module receives 5 peak Sun Hours per Day. 3. Calculate the number of modules needed to produce the power calculated in step 1. 4. If the average price per watt of PV module is $5.00, calculate the cost of the array(s). 5. Assume total Cost Balance of System Components (BOS) is $8000, Calculate the total system cost (cost of arrays + BOS). 6. If the tax credit is 30% of the total cost, calculate the \"simple payback period\" for the PV project if the price of kWh is 25 cents (grid price rate). 7. Assume PV lifetime of 25 years. A 25-year loan was taken out to pay for the project with an interest rate $i = 8\%$, Calculate the annual payment cost. 8. Calculate the price per kWh to break even. 9. Is the price per kWh from PV system lower than the grid price rate? 10. What changes can be made in the system design to reduce kWh price rate for the PV system?

As discussed in the notes (and on p. 438 of the text), Kierkegaard identifies what he calls the \"aesthetic stage of life.\" The character of Don Juan is given as an example of someone who is in the aesthetic stage. For this forum, I'd like you to identify a figure from popular culture (i.e., a character from a book, movie, or TV series) that meets Kierkegaard's description of one who is in the aesthetic stage of life. (Remember to offer explanations in defense of your choice.)
