Worth noting.
Incidentally...
This smells like George Sore-Ass...
If the mean is 9.96, but you have one case of 113 ng/mL, then the mode is likely a lot lower than 9.96, and so also less than 11.
I see you don't know how to play nice with numbers either.
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count. If the mean, or average is 9.96; then 11 is higher than the average for the given 541 individual sample of fentanyl overdose fatalities..
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
"In this study, 541 individuals were identified who died of fentanyl-induced overdose in New Hampshire from January 1, 2015 to September 30, 2016."
You should have read it, you old fool. Your grumpy old man act is not working. Next time look up mode and at least you will know what it means.
Going with your ignorant statistical fudge, if the average overdosed dead body scored 9.96; and the mode were 1.0 (very significantly lower than 9.96); what would that say for poor George Floyd at 11. Would that mean he was eleven times dead? How did you think you were helping your argument by saying the most commonly found fatal dose of fentanyl was less than eleven? Likely a lot lower than 9.96? You should at least try to fudge your statistic in a favorable direction. Nope. You seem to get everything bass ackwards.
I am glad to see that you agree that 11ng/mL works as a lethal dose, without any help from arteriosclerotic heart disease, multifocal, severe; hypertension; or a knee to the neck.
