Hi Norm
Sounds like a pretty good outcome.
As sample size increases, the experimental mean and standard deviation become closer to what could realistically be expected.
15/21 is 28.57%, down from 36.36%. Sounds like this experimental data is the opposite to what is actually happening in the world.
But then again, a good percentage of the idiots probably went 4 stroke or electric or battery years ago.
Glad that most of the engines are good, how many are chinese blocks?
