Q.In a Random Sampling distribution of means : I. The standard error will decrease as the sample size increase. II. The standard error will increase as the sample size increases. III. The mean equals the population mean. IV. The mean is not equal to the population mean. Code :
Correct answer: I and III
Explanation
Random sampling is also known as probability sampling or chance sampling. In this sampling design every item of the universe has an equal chance of inclusion in the sample in a random sampling distribution of means the standards error will decrease as the sample size increases, the mean equals the population mean.
