I don't wanna do any more maaattthhhhh *crying*
I'm going to bed..
we have the number fixed :16k
we have the total number insured: 70k
I think setting the equation to zero is more algebraic though, not cal. Although cal is algebra. It doesn't require cal knowledge to do. So yes, let's get a high schooler to do this, or we can just use their estimated number of ~34% and find a distribution. Although this 34% might already be one or two standard deviations up. I think they know their math, so I'm going to say they've seen something like a 29% total failure rate over those years with a standard error 2-3%, and a certainty (or whatever it's called) of 67%+ (based on the sample size vs total size). But there is probably a lot more we can find from that. I'm not willing to do 10 minutes of work to figure it all out though, especially if they don't themselves know the total failures.
