A plywood company makes plywood for use in furniture production. In the first major step in the plywood process, a lathe rotates the logs through a knife that peels the log into layers. Ideally, when a log is reduced to a 4-inch core diameter, the lathe releases the core. Before peeling, the logs are conditioned in a heated water-filled vat to warm them. Two factors are believed to affect the core diameter: the vat temperature and the time the logs spend in the vat prior to peeling. The lathe supervisor recently conducted a test during which logs were peeled at each combination of temperature and time. The data are the core diameters in inches. Complete parts a through d.

A company makes dog food at four different plants and in four different formulas. One of the ingredients is of particular importance: crude fat. To discover if there is a difference in the average percent of crude fat among the four formulas and among the production sites, the sample data in the accompanying table were obtained. Complete parts a through c below. Click the icon to view the data table of the percentage of crude fat. a.
