Exercise 11-9 Algo A research analyst is examining a stock for possible inclusion in his client's portfolio. Over a 17-year period, the sample mean and the sample standard deviation of annual returns on the stock were 20% and 14%, respectively. The client wants to know if the risk, as measured by the standard deviation, differs from 19%. (You may find it useful to reference the appropriate table: chi-square table or F table) a. Construct the 99% confidence intervals for the...

Consider the following sample data: x 13 3 5 15 6 y 389 206 97 35 6 b-1. Calculate the sample covariance. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Sample covariance b-2. Interpret the sample covariance. The covariance indicates that x and y have a positive linear relationship. The covariance indicates that x and y have a negative linear relationship. The covariance indicates that x and y have no linear relationship....
Consider a sample with 10 observations of 11, –3, 8, 8, 10, 1, –2, 13, 8, and –4. Use z-scores to determine if there are any outliers in the data; assume a bell-shaped distribution. (Round your answers to 2 decimal places. Negative values should be indicated by a minus sign.) The z-score for the smallest observation The z-score for the largest observation There are outliers or no outliers in the data. The historical returns on a portfolio had...
