Information is needed to describe phenomena. When data have been collected

Information is needed to describe phenomena. When data have been collected, tabulation and summarization make the data more manageable and meaningful. If this is our goal, we are concerned with descriptive statistics.

Part 1: A manufacturer of MP3 players surveyed 100 retail stores in each of the firms sales regions. An analyst noticed that in the South Atlantic region the average retail price was $165 (mean) and the standard deviation was $30. In the Mid-Atlantic region the mean price was $170, with a standard deviation of $15. What do these statistics tell us about these two sales regions?
