What is a simple random sample?
- In statistics, a simple random sample is a subset of individuals selected at random from a larger population with an equal probability of selection.
- This technique involves picking a sample at random.
- Major advantages include its impartiality and simplicity.
- Some of the disadvantages include the challenge of acquiring a list of a larger population, the time commitment, the expense, and the potential for bias to still exist.
So, a population with p = 0.40 is chosen at random, with a size of 100.
So, 0.40 is the anticipated value.
Therefore, in the simple random sample, the expected value id 0.40.
