Question Details

The standard error of an estimate is the standard deviation 



TRUE OR FALSE:

1.	An unbiased estimate is a point estimate such that the mean of its sampling distribution is equal to the true value of the population parameter being estimated.

	

	2.	A probability sample is a sample in which the sampling units are chosen from the population by means of a random mechanism such as a random number table.

	

	3.	The standard error of an estimate is the standard deviation of the sampling distribution of the estimate. It measures how much estimates from different samples vary.

	

	4.	Ideally, we prefer estimates that have large standard errors.

	

	5.	The standard error of sample mean   is large when the observations in the population are spread out (large  ), but that the standard error can be reduced by taking a smaller sample.
