Textbook Question
Chapter 12.1, Problem 5P
- Draw a (fairly long) line segment and designate it as being 1 unit long. Then draw a 0.6-unit-by0.9-unit rectangle.
- Apply the length width formula for the area of the rectangle and verify that the formula gives you the correct area for your rectangle in part (a). Attend carefully to units of area.
- When you appIied the length ~width formula to fund the area of the rectangle in part (b), you used lengths of 0.6 and 0.9 units. Describe these lengths and show them in your drawing.

At a shooting range, instructors can determine if a shooter is consistently missing the target because of the gun sight or because of the shooter's ability. If a gun's sight is off, the variance of the distances between the shots and the center of the shot pattern will be small (even if the shots are not in the center of the target). A student claims that it is the sight that is off, not his aim, and wants the instructor to confirm his claim. If a skilled shooter fires a gun at a target multiple times, the distances between the shots and the center of the shot pattern, measured in centimeters (cm), will have a variance of less than 0.33. After the student shoots 28 shots at the target, the instructor calculates that the distances between his shots and the center of the shot pattern, measured in cm, have a variance of 0.25.

He surveys a simple random sample of 279 recent articles published by reputable mathematics research journals and finds that 123 of these articles have US authors.
