The answer to your question would be 3/25 because if you divide 12 by 2 it is 6 and then 100 by 2 is 50 then 6 divided by 2 is 3 then 50 by 2 is 25 thats how you get the answer of 3/25

You observe a portfolio for five years and determine that its average annual return is 13% and the standard deviation of its ret
horrorfan [7]

Answer:

There is a 95% probability that the portfolio would not loose more than 30% of its value.

Step-by-step explanation:

The confidence interval for proportions (<em>p</em>) is:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

The information provided is:

\hat p = 0.13\\\sqrt{\frac{\hat p(1-\hat p}{n}} =0.21

For 95% confidence level the critical value of <em>z</em> is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

The 95% confidence interval for average annual return is:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\=0.13\pm 1.96\times0.21\\=0.13\pm 0.4116\\=(-0.2816, 0.5416)\\\approx(-28\%, 54\%)

The lower limit of the 95% confidence interval is -28%.

This implies that the portfolio would not loose more than 28% of its value.

Thus, there is a 95% probability that the portfolio would not loose more than 30% of its value.
