A self-proclaimed health and wellness company

A self-proclaimed health and wellness company contracted statisticians to examine
the efficacy of their newly developed dieting program. They provided the statisticians with
data from a publicized weight loss competition that they hosted to advertise the release of
their new product. For the competition, participants completed the dieting program and
were ranked in order of the amount of weight they lost pre- and post-completion of the
program. What statistical analysis could the statisticians perform to assess the efficacy of
the dieting program?
