Final answer:
The length of time it takes for an employee to complete an assembly procedure at an automotive plant is not a ratio level variable.
Step-by-step explanation:
The statement that a variable, such as the length of time it takes for an employee to complete an assembly procedure at an automotive plant, is a ratio level variable is FALSE.
Ratio level variables have a meaningful zero point, which means that zero indicates the absence of the quantity being measured. In the case of the employee's completion time, zero time would not indicate the absence of completion, but rather that the assembly procedure has not started. Therefore, the employee's completion time is not a ratio level variable.
