2. A town's government is looking into its residents' opinion on rebuilding the boardwalk on their
coastline. Two representatives from the town visit the existing boardwalk and randomly survey
50 people to see whether they support the new boardwalk. They find that 62% of those surveyed
support the construction of the new boardwalk and conclude that with 90% confidence, the
majority of residents support its construction. What aspect of this scenario brings the validity of
this conclusion into doubt?
The 90% confidence interval includes values below 50%.
The sample might not be representative of the population of interest.
The sample size is not large enough.
The conclusion does not report the standard deviation or the confidence interval.
