1. Data have to be collected to measure the effectiveness of an advertising campaign in a particular morning newspaper in an American city. For this situation, describe how one can collect samples using different sampling plans such as simple random sampling, stratified sampling, and cluster sampling. 2. Compute the mean and standard deviation of the runs scored by the 30 teams in major league baseball in the year 2010 (data given in the Excel file Major League Baseball). Now draw a random sample of six teams using an appropriate random number generator in Excel. Compute the mean and standard deviation of the runs scored by the selected teams. How does it compare with the population quantities?
