Final answer:
The Age Discrimination in Employment Act protects workers who are 40 years of age or older, with no upper age limit, making the statement false.
Step-by-step explanation:
The statement that the Age Discrimination in Employment Act (ADEA) only protects workers from age 40 to age 70 is false. The ADEA, which was passed in 1967, prohibits employment discrimination on the basis of age against individuals who are 40 years of age or older, without specifying an upper age limit. This means that protections under the ADEA are not capped at age 70 and continue to apply to workers beyond that age as well.
