- n. The state, property, or extent of not overlapping.
Sorry, no etymologies found.
The confidence interval is calculated by the sample size the individual risk ratios (for the experimental groups) and the p level setting and for this type of data you look for nonoverlap of the interval with 1 (which is the studies showed equal risk).
a few extra motherboards, most necessarily it won't get you to 100 years, but assuming you pack away 4, and 2 die in the first 30 years, it will get you past 50 years at least and, with hard work, and assuming nonoverlap in what part failed, you could cannibale parts to get at least one still working for a very long time
