Confidence interval for a mean and one-sample t-test. As the world warms, the geographic ranges of species might shift toward cooler areas. Chen et al. (2011) studied recent changes in the highest elevation at which species occur. Typically, higher elevations are cooler than lower elevations. Below are the changes in highest elevation for 31 taxa, in meters, over the late 1900s and early 2000s. (Many taxa were surveyed, including plants, vertebrates, and arthropods.) Positive numbers indicate upward shifts in elevation, and negative numbers indicate shifts to lower elevations. The values are displayed in the accompanying figure.

f. What value of α is needed for a 95% confidence interval?
g. What is the critical value of t for this α and number of degrees of freedom?

It is well-known that an American call option written on non-dividend paying stock shouldn’t be exercised early. Please explain why an American futures call might ever be worth exercising early, even if the underlying stock of the futures doesn’t pay any dividend. (Hint: what is the risk neutral probability for pricing future option, and what is the risk neutral probability for pricing a stock option where the stock is dividend paying?)
