Whether thegiven sentence is unbiased or biased.

Answer to Problem 12.1.2EP
The sentence is unbiased systematic.
Explanation of Solution
Given information:
The given sentence is “Every fifth car is selected from the assembly line. The cars are also identified by the day of the week during which they were produced.
Calculation:
The sample is to select a fifth car from the assembly line. This is an unbiased systematic random process because the fifth car has been identified by specific day of the week which they have been produced.
Therefore, the sentence is unbiased systematic.
