About 1905 Einstein published a work about diffusion of hard
spheres and brownian motion. One effluence of that is the so called
"Viscosity Equation" which was/is very important for dertermining
moleculat weight of macromolecules by viscosity of solutions.

What I like to know: Was there any relation to the other
topics Einstein worked on? Is something known on Einsteins
reason
work on Viscosity?

Describe how allele frequencies change due to random genetic
drift in a small population versus a large population, showing an
example of calculating the probability of drift leading to loss of
an allele in a small diploid population of size 10, versus a
population of size 100.

Small Mean Problem. Grandfather clocks have a
particular market in auctions. You are given a random
sample of 20 purchases of grandfather clocks at auctions in
Pennsylvania. The sample statistics are:
Mean = $1,343.04
Std Dev = $414.04
C.V. = 30.83
N = 20
You are asked to create a 90% Confidence Interval around the
price for this sample.
