Suppose that observations on a stock price (in dollars) at the end of each of 15 consecutive weeks are as follows:

30.2, 32.0, 31.1, 30.1, 30.2, 30.3, 30.6, 33.0, 32.9, 33.0, 33.5, 33.5, 33.7, 33.5, 33.2

Estimate the stock price volatility. What is the standard error of your estimate?

(Hint: A template solution table is provided below for your easy reference. After calculating the u column, you need to use the sigma u and sigma u^2 to use the formula to compute the standard deviation)
