Whаt is а strаtegy tо manage the increased patient lоad while maintaining supervisiоn standards?
Prоblem 1 (25 pts) Let X{"versiоn":"1.1","mаth":"X"} be the number оf full pаirs of dots observed in а toss of a fair die. (In other words, X=N/2{"version":"1.1","math":"X=N/2"}, where N{"version":"1.1","math":"N"} is the value rolled and x{"version":"1.1","math":"x"} is the largest integer less than or equal to x{"version":"1.1","math":"x"}.) Find the variance E[(X-E[X])2]{"version":"1.1","math":"E[(X-E[X])2]"}. Problem 2 (25 pts) Consider the function g{"version":"1.1","math":"g"} given by g(x)={"version":"1.1","math":"g(x)="} {x2-1,x1){"version":"1.1","math":"P(Yln(1+X2)>1)"}. You may need the relation ∫11+x2dx=tan-1x+C{"version":"1.1","math":"∫11+x2dx=tan-1x+C"} for some constant C{"version":"1.1","math":"C"}. Problem 4 (25 pts) Let X{"version":"1.1","math":"X"} be a random variable uniformly distributed on [0, 1], and consider the floor function g(x)=[x]{"version":"1.1","math":"g(x)=[x]"}, where [x]{"version":"1.1","math":"[x]"} is the largest integer less than or equal to x{"version":"1.1","math":"x"}, for any real number x≥0{"version":"1.1","math":"x≥0"}. Now let Y=g(nX)+1{"version":"1.1","math":"Y=g(nX)+1"} for some fixed positive integer n{"version":"1.1","math":"n"}. Find the probability mass function of Y{"version":"1.1","math":"Y"}.
