# Survival time of components - what approach

Hey,

Some electronic components have had their time to breakdown x, recorded. During manufacturing they have been hardened for different amounts of time, t.

Code:
t                      x
0.5   0.094  0.067  0.067  0.119
1     0.306  3.834  0.649  0.323
2     1.211  0.538  1.544  0.188
3     0.496  3.038  0.052  4.065
4     0.878  1.539  6.019  1.768
5     0.528  1.372  2.158  6.943
I have to determine if the time to breakdown x, is related to the hardening time t.

Since the response variable is continuous, and the explanatory variable is ordinal (?), should I then use Analysis of Variance?

It's given in the problem that E(x) when hardening time is t, is E(xt) = 1 / (a + (B/t) )
