In the following two completely unrelated scenarios discuss which choice in each scenario would be the better sample size option. Explain your reasoning for each choice for each scenario.
Scenario 1 determine proportion of people over six feet tall:
A representative sample of size 100 from a population of size 100,000.
A representative sample of size 1,000 from a population of size 100,000,000
Scenario 2: determine proportion of people that have blue eyes:
A representative sample of size 100 from a population of size 100,000
A representative sample of size 100 from a population of size 1,000,000
Homework Answers
Scenario 1 determine proportion of people over six feet tall:
A representative sample of size 100 from a population of size 100,000.
This is because it is not unusual to find a proportion of people over six feet and this sample size would be enough from an average poll of people.
Scenario 2: determine proportion of people that have blue eyes:
A representative sample of size 100 from a population of size 1,000,000
This is because it is unusual to find a proportion of people that have blue eyes. So, a large people poll is required to meet the success and failure requirement.

Left Foot Syndrome is a rare condition in which individuals are born with two left feet if they are homozygous for a recessive r allele (w) genotype, those who are heterozygous (Rr) and homorygous (RR) are born with correct set of feet one right foot and one left foot. However because people wear shoes, the actual number of double left foot people are not known. Last year, there were 38,972 deaths in the population and of those 117 individuals were...

Suppose that 905 smokers each
received a nicotine patch, which delivers nicotine to the
bloodstream at a much slower rate than cigarettes do. Dosage was
decreased to 0 over a 12 week period. Of these 905 people, 255 were
still not smoking 6 months after treatment. Assume this sample is
representative of all smokers.

In each of the following scenarios, determine if the data are paired. We would like to know if Intel's stock and Southwest Airlines' stock have similar rates of return. To find out, we take a random simple of 50 days, and record Intel's and Southwest's stock on those same days. We randomly sample 50 items from Target stores and note the price for each. Then we visit Walmart and collect t the price for each of those same 50 items....

In general, what could be some issues with this question and how it is worded? Scenario 2: Suppose a...
