Q1 Continuous background. 1 Point Consider a continuous random variable with probability density function f(:c) and cumulative density function F(m) that are continuous over the interval [(1, b]. Mark what's true. C] P'r[X E [a,b]] : F(b) F(a) C] P'rlX 6 [a,b]] : f: mm C] There isy E [0,, b] such that PT[X 6 [a,b]] = f(y)(b a) |:] Fora function, f(:c), that is increasing over the interval [a,b], f(a)(b a) g P'r[X 6 [Mil S f(b)(b 02)- :] F(b) = ff f(m)d:n
