What type of graph would you use to depict the relationship between: Is the number of days in the Intensive Care Unit(ICU LOS) related to gender? If ICU LOS were two different variables and one was coded as categorical and the other as continuous, would you use the same graph to depict the relationship between the variables? For example: 1. # of days in ICU(as a continuous variable) and gender.. 2. # of days in ICU(as a categorical variable) and gender. Would you use the same graph for numbers 1 and 2? Which graphs would you choose?

Teachers get courses assigned to teach each semester. For each instructor, there are the courses that the instructor can teach based on the skill set of the instructor, and there are courses that the teacher would rather teach all the time, closer to their specialization. To be able to teach in any department, a teacher must be able to teach more than the favorite courses. Let X denote the proportion of teachers who teach the whole spectrum of courses taught in a department, and Y the proportion of teachers who teach the courses they specialize in. Let X and Y have the joint density function : f(x,y)=2(x+y),0<y<x<1 (a) Given that 10% of the teachers teach the whole spectrum of courses, what is the probability that fewer than 5% teach their favorite courses? (b) What is the expected percentage of teachers teaching their favorite courses when the proportion of teaching the whole spectrum is 0.7?
