A researcher wishes to estimate, with 95% confidence, thepopulation proportion of adults who support labeling legislationfor genetically modified organisms (GMOs). Her estimate mustbe accurate within
5% of the true proportion.
(a) No preliminary estimate is available. Find the minimumsample size needed.
(b) Find the minimum sample size needed, using a priorstudy that found that 68% of the respondents said they supportlabeling legislation for GMOs.
(c) Compare the results from parts (a) and (b).
Part 1
(a) What is the minimum sample size needed assuming that noprior information is available?
