Expert Solution & Answer
Chapter 7, Problem 6SG
Explanation of Solution
Pointer:
In a graphical user interface, a pointer is a small symbol on the screen. When a user moves a pointing device, then its location and shape will be changed.
- It indicates the point where the user action took place...
Explanation of Solution
List of objects a pointing device can select:
A pointing device can enable the user to select texts, graphics, and other objects, such as icons, buttons, menus, and links. Some pointing devices are mouse, trackball, and digital pen.
- Trackball: A trackball is a fixed pointing device with a ball on its top or side. The ball in most trackballs is about the size of Ping-Pong ball.
- Mouse: Mouse is a pointing device that easily fits under the palm of your hand...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
