19. A furnace manufacturer wants to know how much of the metal surface area is giving off heat in this design. The metal box is cube-shaped (all sides equal) with sides measuring 40 in. The circular metal vent is 30 in tall with a diameter of 8 in. Calculate the surface area giving off heat, excluding the cube's base and the bottom and top of the vent tube. (Hint: You must also subtract the area of the circle where the vent connects to the cube.)

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?
