2) In an evaluation study I wanted to examine the relationship between gender, ethnic background, and students' attitudes toward the role of chance in their lives. Given the following data, estimate $R^2$ and interpret it. Source SS F P Gender 962.237 2.693 0.101 Ethnicity 7380.295 5.165 0.000 Gender X Ethnicity 3591.516 2.513 0.041 Error 168269.148 Select one: A. $R^2$ is about 6% meaning 6% of the variation in attitude toward chance is explained by ethnic background and the interaction effect. B. $R^2$ is about 6% meaning 6% of the variation in attitude toward chance is explained by gender, ethnic background, and their interaction effect. C. $R^2$ is about 2% meaning that 2% of the variation in attitude toward chance is explained by the interaction effect. D. $R^2$ is about 4% meaning that 4% of the variance in attitude toward chance is explained by ethnic background.

Its product is priced at $300 per unit. Product costs include: Direct materials $90.00 Direct labor $66.00 Variable overhead $15.00 Total fixed factory overhead $440,000 Variable selling expense is $12 per unit; fixed selling and administrative expense totals $290,000. Olivian has a tax rate of 40 percent. Required: 1. Calculate the before-tax profit needed to achieve an after-tax target of $600,000. 2. Calculate the number of units that will yield operating income calculated in Requirement 1 above. If required, round your answer to the nearest whole unit. units 3. Prepare an income statement for Olivian Company for the coming year based on the number of units computed in Requirement 2. Do NOT round interim calculations and, if required, round your answer to the nearest dollar. Olivian Company Income Statement For the Coming Year Total What if Olivian had a 35 percent tax rate? Would the units sold to reach a $600,000 target net income be higher or lower than the units calculated in Requirement 2? Lower Calculate the number of units needed at the new tax rate.

Air having a freestream velocity of V∞ = 3 m/s and free stream temperature of T∞ = -10 °C is flowing steadily parallel to the wall of a building. The dimensions of the wall are 35 m length, 35 m width, and 30 cm thickness. In addition, the wall outside surface temperature is kept at 0 °C, while the indoor air temperature of the building is kept at 22 °C. Assume that the convective heat transfer coefficient on the inside surface of the wall is 8 W/m^2K, and radiation heat transfer is neglected. Calculate: a) the convective heat transfer coefficient on the outside surface of the wall [W/m^2*K]. obs: the conclusion of this one is telling us that the Xcr is = 2.16 m. and that the flow is fully turbulent. Please explain why, and what the critical number tells us about external flow. The conclusion also gives this answer: Nu = 0.03*Re^0.8 * Pr^1/3 = 3062 Ho = Nu*k/L = 2.03 W/m^2*K
