Given the task definition and input, reply with output. In this task, you're given a pair of sentences, sentence 1 and sentence 2. Your job is to determine if the two sentences clearly agree/disagree with each other, or if this can't be determined. Indicate your answer as yes or no respectively.

Sentence 1: While this is a proxy for labor and non labor costs, it is considered realistic since in the U.S., the use of workforce full time equivalents provide estimates within a few percentage points of those calculated with labor and non labor costs. Sentence 2: Workforce full time equivalents do not give estimates anywhere close to those derived from labor and non labor costs.
