Interpreting Graphs 1. Mr. Candreva class grades were graphed as a pie graph. Based on this a) The largest percentage of students received what grade? b) Estimate what percentage of the class received a d Estimate what percentage of the class received an A d) Based on the graph, do you think Mr. M's class is difficult? Why or why not?

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.
