An investment specialist claims that if one holds a portfolio that moves in the opposite direction to the market index like the All Ordinaries Index, then it is possible to reduce the variability of the portfolio's return. In other words, one can create a portfolio with positive returns but less exposure to risk. A sample of 26 years of the All Ordinaries index and a portfolio consisting of stocks of private prisons, which are believed to be negatively related to the All Ordinaries index, is collected. A regression analysis was performed by regressing the returns of the prison stocks portfolio (Y) on the returns of the All Ordinaries index (X) to prove that the prison stocks portfolio is negatively related to the All Ordinaries index at a 5% level of significance. The results are given in the following Microsoft Excel output. Referring to the information above, to test whether the prison stocks portfolio is negatively related to the All Ordinaries index, the measured value of the test statistic is: - 0.072 - 0.357 - 7.019 - 0.503 An investment specialist claims that if one holds a portfolio that moves in the opposite direction to the market index like the All Ordinaries Index, then it is possible to reduce the variability of the portfolio's return.

1. The floor plan for a single story residential building in Lafayette LA is shown in the following figure. The building is 8 ft tall with a flat roof. The window-to-wall area ratio is 0.25. 72 ft- 36 ft The design data is summarized in the following table. ? North Item Heating Cooling Indoor DB (°F) 70 75 Indoor RH (%) N/A 50% Outdoor DB (°F) 30 95 Outdoor WB (°F) N/A 78 Daily DB Range (°F) N/A 16 Internal heat gain (W/ft² floor N/A 0.75 area) Solar irradiance (W/ft² N/A 30 exterior surface area) Building characteristics are listed in the following table. Component Factors Roof U=0.036 Btu/h-ft²-°F ?=0.85 Exterior wall U=0.083 Btu/h-ft²-°F Windows U=0.67 Btu/h-ft²-°F Window shading factor SHGC=0.37 SF=0.7 Also, a combined rate of ventilation and infiltration was estimated to be 100 ft³/min in both cooling and heating operations. The loss coefficient for the air distribution system is $F_{loss}$ = 0.15. Calculate the cooling and heating loads for the residential dwelling. The cooling load factors and fenestration solar load factor are shown in the following tables. Determine the cooling (sensible and latent) load and the heating load for this residential building.
