At Mimi's preschool, Friday is pizza day, and all of the 60 students look forward to getting their own slice. Mrs. Cornejo was part way through cutting each of the ten pizzas into 6 slices when she discovered one of the pizzas was completely burnt. She decided to cut the remaining pizzas into seven slices and some into eight slices so there would be enough to go around. How many pizzas might have been cut into six slices? Seven slices? Eight slices?

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
