Answer:
the seeds of plants contain angiosperm (flowering plants) seeds consist of three genetically distinct constituents: (1) the embryo formed from the zygote, (2) the endosperm, which is normally triploid, (3) the seed coat tissue derived from the maternal tissue of the ovule.
Nonpoint source pollution comes from several locations. If they cannot find the origin of the pollution it can be almost impossible to regulate. Or they may not have enough funding.
Subjects in the population are sampled by a random process, using either a random number generator or a random number table, so that each person remaining in the population has the same probability of being selected for the sample.
How to Estimate a Population Total from a Simple Random Sample
1. This lesson describes how to estimate a population total, given survey data from a simple random sample. ...
2. Sample mean = x = Σx / n.
3. Population total = t = Nx.
4. where N is the number of observations in the population, and x is the sample mean.
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. ... In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.
Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
