Solution:
1. Dado:
- Distancia horizontal desde el observador hasta la base del globo: d = 150 \ m
- Ángulo de elevación: \theta = 40^{\circ}

2. Usamos la función tangente para encontrar la altura h del globo aerostático. La tangente de un ángulo en un triángulo rectángulo es la razón entre la altura y la distancia horizontal:
\tan(\theta) = \frac{h}{d}

3. Sustituimos los valores conocidos en la ecuación:
\tan(40^{\circ}) = \frac{h}{150}

4. Resolvemos para h:
h = 150 \times \tan(40^{\circ})

5. Calculamos el valor numérico:
* Usando una calculadora, \tan(40^{\circ}) \approx 0.8391
* Entonces: h \approx 150 \times 0.8391 = 125.865 \ m

La altura del globo aerostático es aproximadamente 125.865 \ m.

A mutual fund manager has a $350 million portfolio with a beta of 1.10. The risk-free rate is 3.5%, and the market risk premium is 6.00%. The manager expects to receive an additional $150 million which she plans to invest in several different stocks. After investing the additional funds, she wants to reduce the portfolio’s risk level so that once the additional funds are invested the portfolio’s required return will be 9.20%. What must the average beta of the new stocks added to the portfolio be (not the new portfolio’s beta) to achieve the desired required rate of return?

We plan to test whether the mean mRNA expression level differs between two strains of yeast, for each of 8,000 genes. We will measure the expression levels of each gene, in n samples of strain 1 and m samples of strain 2. We plan to compute a P-value for each gene, using an unpaired two-sample t-test for each gene (the particular type of test does not matter). a) What are the null hypotheses in these tests (in words)? [2] b) If, in fact, the two strains are identical, how many of these tests do we expect to produce a P-value exceeding 1/4? [2]
