Read the following premise and answer if the hypothesis is true.
The 1921 NCAA football season had no clear-cut champion, with the "Official NCAA Division I Football Records Book" listing California Golden Bears, Cornell Big Red, Iowa Hawkeyes, Lafayette Leopards, Washington & Jefferson Presidents, and Vanderbilt Commodores as champions. Only California, Cornell, and Lafayette claim national championships for the 1921 season.
Hypothesis: The Iowa Hawkeyes did not win the national championship in 1921.. Is the answer "Yes", "No", or "It's impossible to say"? Respond with only the answer and no additional text.
No
Yes.
