- 1)Stocked Quadrat is easy to just establish whether or not the species of interest is present.
- A quadrat in which the
species of interest is present is said to be stocked. - If y is the number of plots
in our sample of size n that are not stocked, then y/n is an estimator of
the probability of a plot not being stocked - 14)sessile or relatively immobile organisms
- For a forest community
- Vegetation patterns
- The amount and time based on population
- 15)seaonal changes
- Different species counted in the same quadrant
- If animals are moving during sample period

If possible could you show me how to do this in excel? Weights of a population have a mean (µ) of 180 pounds and standard deviation (σ) of 15 pounds. If random samples of size n = 5 are selected from this population, what percentage of the sample means would you expect to be (or “What is the probability that any sample mean (x-bar) is”) 1. (6 points)Between 179 and 181 pounds? 2. (6 points)Less than 177 pounds?

3. (13 marks) The population of a small town was 20,000 on January 1st, 2010 and has grown at a rate of about 2% per year since then. Next year, the local high school is closing and this is likely to affect the population of the town as people move away to towns with more schools. (a) Write down a model of the population of the town for the years 2010 to 2019. Carefully define any variables you use and...

The Census Bureau groups data on households into census tracts,
where each census tract has a total population of about 4,000
residents. Census tracts should be divided so that the households
in the census tracts share certain characteristics, such as
economic status. Even though most tracts are around 4,000
residents, there is some variability, which is the focus of this
lab. In practice, census tracts usually have a population between
1,200 and 8,000 people.
