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?
