3. A failure density function f(t) is given by: f(t) = (ß/n³) (tß-1) exp [-(t/n) ³] A cumulative failure density function, F(t) is given by: F(t) = 1-exp [-(t/n) ³] What

is the reliability function, R(t)? What is the hazard rate (failure rate) function, h(t)? What can be said about the failure rate for ẞ equal to 1, less than 1 and greater than 1?
