How do you calculate sample size for survey of city having population 800000?

That depends on what you want to know, the form of the answer, how and where the survey is to be conducted and lots of other variables. Once you have all of that sorted, the best and simplest method is to consult tables or software.

Difference between calculating the sample mean and the population mean?
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
What sentence is a true statement Is a sample a subset of the population or Is a population a subset of the sample?
A sample is a subset of the population.
How is a sample different from a population?
The sample is a subset of the population.
What is a sample that that consists of everyone in the population?
It is not a sample. A sample must be a proper subset of the whole population.
What is the difference between calculating the sample mean and the population mean?
You calculate the actual sample mean, and from that number, you then estimate the probable mean (or the range) of the population from which that sample was drawn.

How does one calculate the standard error of the sample mean?
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
What is subset of a population called?
A Sample

What sentence is a true statement Is a sample a subset of the population or Is a population a subset of the sample?
A sample is a subset of the population.
What will happen if the sample you have drawn from the population does not represent the population?
You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.
How is a sample related to a population?
A sample is a subset of the population.
How is a sample different from a population?
The sample is a subset of the population.
Is the data is sample or population?
Data is neither sample nor population. Data are collected for attributes. These can be for a sample or a population.
What is a sample that that consists of everyone in the population?
It is not a sample. A sample must be a proper subset of the whole population.
How does a sample size impact the standard deviation?
If I take 10 items (a small sample) from a population and calculate the standard deviation, then I take 100 items (larger sample), and calculate the standard deviation, how will my statistics change? The smaller sample could have a higher, lower or about equal the standard deviation of the larger sample. It's also possible that the smaller sample could be, by chance, closer to the standard deviation of the population. However, A properly taken larger sample will, in general, be a more reliable estimate of the standard deviation of the population than a smaller one. There are mathematical equations to show this, that in the long run, larger samples provide better estimates. This is generally but not always true. If your population is changing as you are collecting data, then a very large sample may not be representative as it takes time to collect.
