Example 13 (Exercise 4.91, 6th edition, Exercise 4.87, 5th edition): The failure time observations (1000’s of hours) resulted from accelerated life testing of 16 integrated circuit chips of a certain type. Use the corresponding percentiles of the exponential distribution with =1 to construct a prob ...

... This question amounts to asking what is P(t≥3.55) given N-1=34 degrees of freedom. The t tables that I’m using shows that this is less than 0.01. So given that the average person goes to the bathroom 4.5 times per day, with a standard deviation of 1.0 times, there less than a 1% chance of randomly s ...
