premise: The Castaways Hotel and Casino, formerly the Showboat Hotel and Casino was a hotel and casino located at the north end of the Boulder Strip in Las Vegas, Nevada. The hotel consisted of a 19 story tower containing 445 rooms, a casino and an adjacent RV park. The Castaways hotel was demolished on January 11, 2006 to make way for an unknown project.
hypothesis: The Castaways Hotel and Casino averages less than 23 rooms per floor.
reason: The context statement says the hotel is 19 stories with 445 rooms. This calculates to an average of 23.42 rooms per floor. The statement that the hotel averages less than 23 rooms per floor is definitely incorrect.
