People may be interested to know that the 'normality' of the list is
slipping fast! The P value is now only 0.38. A few 'abnormal'
youngsters, more mid 30s than early 40s, the absence of 59-61 yr olds,
the gap between 68 and 73 etc. Still forced to conclude that the list is
'normal' at least by statistical convention.
The strongest fit to the curve is a polynomial one; that is, the curve
is a bit 'wavy'. Although, curve fitting is a bit 'damned lies' as often
a number of shapes can fit 'statistically significantly'.
The mode is now 50, as they have overtaken the 36 year olds. Median now
50 versus mean of 49, so the 50 years olds are the most 'average' by 2
measures out of 3.
Still little evidence of skewness, although it is now slightly
negatively skewed rather than positively skewed, so the youngsters are
pulling extra weight.
Not to far from a normal curve, or a 'bell' one as mentioned. Although,
wasn't the 'bell curve' used in some sort of social darwinist thing
about intelligence or something?? 'Normal' curve seems better.

PS Bernard, great you are compiling the numbers, but it would be a help
to have a little extra bit with the NEW numbers, because it is a bit of
a hassle to convert the format into a single column for the stats.
