So in different solvents solvatochromatic dyes produce different colors based on the gap created by said solvent. So I know that adding electron donating groups raises the HOMO and withdrawing group lower the LUMO, I'm having trouble thinking about the effects this would have on the color. on an unsubstituted dye polar solvents produce a red color and non-polar solvents produce a blue color. My dye that had electron donating groups on it, Would the color spectrum become redder even in non polar solvents and why?

Q2.Calculate the distance to default if the current market value of asset is 300 Million, growth is 3%, asset volatility is 15%, current liabilities are 200 Million, and non-current liabilities are 140 Million, interpret your answer.
If there are 500 firms with this distance to default, and 30 of these have defaulted, calculate the expected default probability, explain in detail the implications this number has for the future default rate?
Distance to default = ((Market Value of Assets) – (Current Liabilities + 0.5 X Non Current Liabilities))/(Market Value of Assets X Asset Volatility)

A diagnostic test has a probability 0.95 of giving a positive result when applied to a
person suffering from a certain disease, and a probability 0.10 of giving a (false) pos-
itive when applied to a non-sufferer. It is estimated that 0.5% of the population are
sufferers. Suppose that the test is now administered to a person about whom we have
no relevant information relating to the disease (apart from the fact that he/she comes
from this population). Calculate the following probabilities:
a) that, given a positive result, the person is a sufferer;
b) hat, given a negative result, the person is a non-sufferer.

36. Point-of-service (POS) plans are similar to those offered by planned provider organizations (PPOs), yet they allow for consumers to select non-plan providers when seeking medical care. Those who choose non-plan providers, however, will be expected to: Select one:
a. Contribute a large percentage of the copayment
b. Excuse themselves from the POS plan after medical services have been received
c. Pay large deductibles on their medical bills before the insurer picks up the bill
d. Pay higher premiums after receiving services.

Problem 2. Let N denote the non-measurable subset of [0, 1], constructed in class and in the book "Real Analysis: Measure Theory, Integration, and Hilbert Spaces" by E. M. Stein, R. Shakarchi.
(a) Prove that if E is a measurable subset of N , then m(E) = 0.
(b) Assume that G is a subset of R with m∗(G) > 0, prove that there is a subset of G such that it is non-measurable.
(c) Prove that if Nc = [0, 1] \ N , then m∗(Nc) = 1.
(d) Now, conclude that
m∗(N ) + m∗(Nc ) ≠ m∗(N ∪ Nc ).
