A researcher approaches you for statistical advice. He wants to estimate the proportion of senior (aged 65+) Canadians who exceed 172 cm in height. He is aware of census information from Statistics Canada that 71% of the target population is female. He is also aware that for study planning purposes he should commit to educated a priori guesses. He uses and as guessed proportions of the female and male subpopulations that exceed 172cm in height. The researcher will sample individuals and measure their height very precisely (to compare to the 172 cm threshold). But he is trying to decide between using a single random sample of 200 from the whole population or separate random samples of size 100 each from the female and male sub-populations. For estimating the target parameter, give the ratio of the anticipated standard error using the second sampling scheme to the anticipated standard error using the first sampling scheme. Report this ratio to two decimal places.
