Consider the case of three treatment status, where we have no treatment, treatment 1 and treatment 2. Let d1 be a dummy variable taking 1 for treatment 1 and 0 otherwise, and d2 be a dummy variable taking 1 for treatment 2 and 0 otherwise.
We consider the following regression
y = α + βd1 + γd2 + ε,
where α, β and γ are parameters and ε is the error with E[ε] = 0. Using β and γ in this regression, explain what you can estimate First, express only the final outcomes mathematically (no derivations) and second, explain each (no more than 10 words for each).

Consider a simple case where we have trained a NN for
recognising patterns X1 to Xn belonging to
some classes, say A and B. Suppose we have a new training data
Xn+1 that belongs to class C. We want this also to be
trained. Will the previous training be impacted? How would it
work?

(a) using the 0.05 significance level, test the null hypothesis
that the three treatment means are equal
(b) Interpret your results.

the null hypothesis that the three treatment means are equal.

Consider a case of single slit diffraction where we are
directing a beam of light (of wavelength λ) through a single slit
of unknown width “D”. The pattern will be observed on a screen a
distance L from the slit. We will be able to take measurements of
the pattern on the screen.
Sketch the pattern you would expect to see and derive an expression
to relate a characteristic length of the pattern on the screen to
the width of...

Consider a process where 15% of the parts produced
have a defect.
If we have a sample of 250 parts, we want to find the probability
that there are between
30 and 45 defective parts in this sample.
i) Calculate the probability that there are exactly 30 defective
parts in the sample.
ii) Write out (but don't calculate) the expression for finding the
probability that between
30 and 45 parts are defective. Hint: use the binomial
distribution.
iii) use the...

Consider a case in which we have an Einstein solid that is
neither at high or low temperature. In this case, we cannot use
either the N>>q or q>>N approximation. In this case
both N and q are >> 1. Derive an expression for the chemical
potential then discuss how this more general result differs from
and/or could correlate to the low and high temperature cases.

5.
We can consider the case where wine producers in Chile ask the
government to tax imported wines from France with a tax. They
consider that this tax would increase both the State's tax revenue
and employment in the Chilean wine industry. What kind of economic
argument is this in relation to international trade? Do you agree
or not with the argument presented by wine producers in Chile? If
the state government adopts this position, does it consider it to...

10. Continuing with the same population in Question 7, let us
consider the case where we picked a sample of size 14. (Do not
worry
about the fact that it is stupid to have a sample of size 14
when the population has only 4 people in it.) What is the standard
error
(deviation) of the sampling distribution of the mean?
