My amazing prints from @lkcreations.art have arrived! Absolutely perfect, complete with certificates of authenticity and a lovely thank you card. Just fabulous. Can’t wait to get them framed and on the wall.

Thanks to @gailmyerscough.co.uk for her fantastic cushions. I am very excited to have them in my mid-century man-cave!
I have not given you (Jack) a direct answer, but we might have a better question. OK, that is enough shouting into the void for today. I’m off to surf patrol at the beach!
So the oximeter compares the absorption of two wavelengths of light - 660 and 940 nm - sampled many (1500Hz +) times per second. The signal has 4 components. A constant amount of 660 absorption, a constant amount of 940 absorption, a variable amount of 660 absorption, and a variable 940 absorption.
@junotk.bsky.social ‘s Thinking About Statistics is an absolute gem.
You’re right. That is a right handed polio blade. The wire runs on the side against the tongue and the bulb shines through a hole in the tongue of the blade - gets the wire out of the way of the ETT and the users vision. I had to look at catalogs on the net.
An alternative idea is that the confidence interval is a single distribution and where you have ended up with your point estimate does give some information on where the result lies. See figure 2.
For the first possibility I am imagining that the confidence interval looks like a straight line drawn across the tops of each distribution of the individually repeated trials covering 95% of the possible outcomes. See figure 1.
This concerns Frequentist Statistics (we can talk about the Good Reverend’s Method another day).
So, everyone. I have gotten sufficiently far into my career of being a Dad, that I have, by and large, become immune to embarrassment. That means I’m happy to ask the kind of questions that may make me look like an idiot. A 🪡
