Answer:
C. With a p-value equal to 0.000, there is statistically significant evidence that the average amount of money spent on hair cuts for women is higher than it is for men.
Explanation:
The P-value, compared to the level of significance, gives us the information to decide if there is statistical evidence or not.
If the P-value is smaller than the level of siginificance, the effect is significant. In this case, with P-value=0.000, it is smaller than any level of significance and we can conclude that there is statistical evidence that there is a difference in the average amount of money spent on haircuts between women and men at UF.
In the output, we have that the t-value is positive. If the Difference is defined as: mu(Female) - mu(Male), we know that the mean spending is higher for women than for men.
Also, the alternative hypothesis is defined as "mu(Female) - mu(Male)>0".
With these, we can conclude the answer is Option C.

Answer:
C. A risk averse investor would choose the economy in which stock returns are independent because risk can be diversified away in a large portfolio.
Explanation:
if stock prices move together, (positive correlation), the volatility of the portfolio will be higher. Higher volatility means higher risk. This is the case with the first economy.
In the second economy however, the stocks are independent of each other meaning there is zero correlation between stocks and hence the portfolio volatility will be much lesser.
As a risk-averse investor you will prefer the portfolio with lower volatility for the same expected return.
