Is sampling with replacement a finite population?
no
What is sampling without replacement?
The representative part of Population is called Sample.
What does it mean when sampling is done without replacement?
Once an individual is selected, the individual cannot be selected again.
Which one is called non probability sampling a. cluster sampling b.quota sampling c. systematic sampling d. stratified sampling?
Answer is Quota sampling. Its one of the method of non-probability sampling.

no
When you sample with replacement are the trials independent?
They are, if the sampling and replacement processes don't introduce any bias.

Why is sampling with replacement used?
Sampling with replacement is used when it is desirable for each item in the population to have an equal chance of being selected each time, and when it is acceptable for the same item to be selected multiple times in the sample. This method is commonly used in bootstrap resampling and in situations where the population is large and well-mixed.
How many samples of size 5 are possible when selecting from a set of 10 distinct integers if the sampling is done with replacement?
105 or 100,000
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
As defined in the text random sampling requires sampling with replacement?
Not necessarily. A random sample can occur with or without replacement, depending on what makes more sense. For instance, trying to calculate the odds of a dice roll would require a random sample with replacement (because it is perfectly possible to get a 6 on each and every die); trying to calculate the odds of a poker hand, however, would require random sampling without replacement (the ace of spades can only show up once in any given round of dealing). when the population size is large enough, the difference between the two is meaningless; people who make national surveys, for instance, usually choose people randomly without replacement (there's no possibility they will survey the same person twice) but treat it as though the were sampling with replacement (because the math is easier). The only requirement for a random sample is that each object that might be chosen has a known and well-defined probability of being chosen at any given moment. For random samples with replacement that probability is always the same; For random samples without replacement that probability is determined by the objects that have previously been selected.

Answer is Quota sampling. Its one of the method of non-probability sampling.
What is sampling in research?
Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.
Is convenience sampling method not a random sampling?
You are correct; convenience sampling is not random sampling.
