Pew Research polled adults in 2018 and 10% of them rated sailboats as the best boat to own. In 2019, Pew Research surveyed a random sample of US adults. Respondents were asked to select the best type of boat from a list of possibilities. Only 48 of the 800 respondents chose the sailboat as the best boat.

In 2013, the Pew Research Foundation reported that "42% of U.S.
adults report that they live with one or more chronic conditions".
However, this value was based on a sample, so it may not be a

normal model may reasonably be used in this setting.
