comment the intuitive difference between expected utility and utility of expected profit in a gambling game
I have never heard "utility of expected profit" before. What do you mean by this?

Look up the "Shapley value" or the "VCG mechanism".

comment A mathematical approach to economics
Standard graduate treatment of microeconomics is: Mas-Colell, Whinston, Green (1995): Microeconomic theory. If you are looking for very rigorous papers, check out articles in the Journal of Mathematical Economics (recent ones, the old ones (80s and prior) are on today's "normal" level).

comment Using regression results to predict?
This is almost right, except you forgot the intercept (always include that if it is estimated) and multiplying the income coeffficient by 1000 is incorrect since it is in 1000. See my answer below.

comment How to perform a monotonic function fitting of data points?
Possibility: find a flexible functional form, possibly nonlinear, fit the coefficients via nonlinear least squares (for example), but constrain parameters such that the function must be strictly decreasing.

Yes, except the interval should be written $[520.17,608.13]$.

comment Statistical Test for Two Group Means
Typically not, since without a measure of variance you cannot judge whether a difference is statistically "big" or "small". Maybe if you had something else like quantiles of the data instead of sd..

comment Intuition and the math behind normalization
I am pretty sure that's not true. Normalizing a draw from a standard normal distribution is the z-score, which is the $\Phi(z)$ percentile. Normalizing a draw from some asymmetric distribution must necessarily for some "z" score yield another percentile, because normalizing is symmetric about the mean while the cdf isn't.
