Chapter 5, Problem 1TC
Explanation of Solution
Given: A Lenovo IdeaPad N580 laptop with a faulty hard drive and a Toshiba MK8009GAH 80-GB 4200-RPM drive
To find: Whether the faulty drive can be replaced with the Toshiba drive or not.
Solution:
A Lenovo IdeaPad N580 has 2.5-inch SATA hard drive, whereas a Toshiba MK8009GAH has a form factor of 1.8 inches and has a UDMA interface.
Hence, option (d) is correct as neither the form factor nor the interface matches.

(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.
