1. A study randomly assigned students attending a large college to different professors for Calculus 1, with equal numbers of students assigned to each professor. The experienced professors were Peters, Parker, and Nguyen. The inexperienced professors were Diaz and Black. The researchers of this study reported students who had experienced teachers for Calculus 1 did better in Calculus 2.

1. List the equally likely outcomes that could occur for assignment on one student to a professor
2. Suppose the event of interest, event A, is that a teacher is experienced. List the outcomes that make up event A.
3. What is the probability a student will be assigned to an experienced teacher?
4. List the outcomes in the complement of event A.
5. List the probability a student will be assigned to an inexperienced teacher.

Epidemiology: which method of sampling controls results in an odds ratio that is equal to the risk ratio in cohort study?

1) Compare and contrast the 3 study approaches (Qualitative, Case-control, and Cohort) including advantages and disadvantages.

The Fitzhugh-Nagumo model for the electrical impulse in a neuron states that, in the absence of relaxation effects, the electrical potential in a neuron v(t) obeys the differential equation

dv/dt = −v[v² − (1 + a)v + a]

where a is a positive constant such that 0 < a < 1.

(a) For what values of v is v unchanging (that is, dv/dt = 0)?  (Enter your answers as a comma-separated list.)
v = ______

(b) For what values of v is v increasing? (Enter your answer using interval notation.)

______

(c) For what values of v is v decreasing? (Enter your answer using interval notation.)

______

Please show all work neatly, line by line, and justify steps so I can learn.

Thank you!
