Question
A researcher wishes to estimate, with
99%
confidence, the population proportion of adults who support labeling legislation for genetically modified organisms (GMOs). Her estimate must be accurate within
4%
of the true proportion.(a) No preliminary estimate is available. Find the minimum sample size needed.
(b) Find the minimum sample size needed, using a prior study that found that
73%
of the respondents said they support labeling legislation for
GMOs.
(c) Compare the results from parts (a) and (b).
