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.

Recall that for an exponentially changing population
N = Noet
And the doubling time is how long it takes for the population to double in size. If you have a
population with r =0.046 , what is the doubling time?
Suppose a population has two alleles at a particular locus, and individuals with different diploid genotypes at this locus have different probabilities of survival and expected offspring, as given in the table below:
Genotype
% Surviving to adulthood
Expected offspring
GG
90%
11
Gg
80%
15
gg
50%
28
Calculate the absolute fitness, W, for each genotype, and then the relative fitness, w, using the smallest absolute fitness value as your reference. Assume that the selection differential s is equal to the difference in relative finesses of the heterozygote, Gg, genotype, and the least-fit genotype. 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? (Give your answer up to four decimal places).
