Question:
Six of the cobot's joint controllers (JC) were tested to failure. The ages at failure (in cycles) were:
| Joint Controller Number | Number of cycles at failure |
| JC1 | 1256 |
| JC2 | 4156 |
| JC3 | 758 |
| JC4 | 903 |
| JC5 | 2487 |
| JC6 | 1909 |
JC6 1909
a. Perform a goodness-of-fit test to determine whether it is reasonable, with 99% confidence, to assume the joint controller data fits an exponential distribution with a failure rate () of 2.865x10-4 cycles.
i. Develop a table and show
ii. Identify the K-S statistic of interest
iii. Define and determine the rejection region
