Q326. (A) Consider this plot of Pn+1 vs. Pn. Without worrying about what sort of system it might be, show that you understand how the chart works by describing the behavior of this system if it starts at time i at Pi=30. How about 70?

(B) If this is a model of attendance at, say, a protest rally with the axes representing percentage of the population, and Pn is how many showed up last week (a number everyone knows) and Pn+1 is how many that means we can expect this week (based on the distribution of individual thresholds - how many people need to be going for me to decide to go), how would you interpret the gaps A and B on the chart?

(C) Think about the "standing ovation model." What features does it add to the basic model described here.
