In a medical research class the students were asked to find out the time of their birth. of the 38 students in the class, 18 were born between 12 am and 11:59 am. If we pick 5 students at random: a) create a probability distributions for the number of students born between 12 am and 11:59 am (A) (label columns and rows; use only what you need; show work-some or all) b) what is the probability of having 2 or...

3. An economics professor went out to dinner one night and observed one of her students partying and having a good time (and obviously not studying). The next day was a final exam. When the professor's husband found out the student was in her class, he said the student's behavior was irrational. The professor disagreed. Under what condition is behavior irrational according to the properties of consumer behavior discussed in the chapter? What situations could make the student's behavior rational?...
