It can get very hot for actors on stage. Not only do they have to remember all of their lines, theater spotlights are usually bright and intense. Independent random samples of spotlights were obtained from four different Broadway theaters (Cort Theater, Imperial Theater, Majestic Theater, and the New Amsterdam Theater). The wattage of each light was measured, and a partial ANOVA summary table is shown below.

t A new section of the San Francisco–Oakland Bay Bridge opened on September 2, 2013. The bridge took over 25 years to complete and cost approximately $6.4 billion. It is open, spacious, and even has a bicycle path, but the “Case of the Corrupt Bolts” lingers.16 Independent random samples of bolts were obtained, and each was subjected to a motion simulating an earthquake. The horizontal displacement of the attached panel was measured for each (in inches). Construct the one-way ANOVA table and test the hypothesis of no difference in population mean horizontal displacement due to bolt type. Use a = 0.01.
