Suppose that you are interested in estimating a population mean. You select a random sample of items, and compute the sample mean and the sample standard deviation.
You then compute a 95% confidence interval to be LCL=28.4 - UCL=37.9.
So what does that mean?
It means that you are 95% confident that the unknown population mean that you are estimating is between the LCL and UCL.
So what does that mean?
It means that if you were to iterate this sampling process many times, say 100, and calculate 100 confidence intervals, then 95 of those intervals will contain the unknown population mean, and 5 will not.
Give me an example of how CI can be used in your work.

Use the Hardy–Weinberg principle to solve problems involving populations.

If there are 311 individuals who are homozygous for the G allele in a population of 4,659, and we ignore the effect of genetic drift, how much should the frequency of the G allele change over one generation of natural selection?

- Suppose that a certain population of salamanders shows (by electrophoretic analysis) genetic variation for a certain enzyme, and that the enzyme appears to be coded by a single gene with two alleles (Ef, Es). Also suppose that the frequency of the two alleles in the population are estimated as p = frequency of Ef = 0.60, q = frequency of Es = 0. 40. Assuming that the population is in Hardy-Weinberg Equilibrium (i.e., all the assumptions of the Hardy-Weinberg model are met), estimate the expected frequency of all possible genotypes in the population.arrow_forwardIn a given population on a distant planet, there are 20 red, 25 orange, and 15 yellow creatures.
