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.

How can you determine the number of bonds an atom can make
Usimov [2.4K]

Answer:

The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.
