Answer #1

A random sample means that each member in the target population (or universe) has an equal chance of being selected. In probability sampling, it is possible to determine which sampling units belong to which sample and the probability that each sample will be selected. In non-probability Sampling, sample does not have known probability of being selected as in convenience or voluntary response surveys.

The correct choice is (C) -  each member of the population has some chance of being included in the sample.

True or False a). A random sample of 1000 students' Statistics scores was drawn from the population of all possible comparable Stat scores (an unknown population/distribution). The sample mean, once computed, has the exact value of the distribution/population mean. b). While trying to figure out the probability that the sample mean for a data of size 10 would exceed a value, we can apply the central limit theorem.
