Transcribed Image Text:**Question:**
The mean of all the sample means obtained from all random samples of a certain sample size in a sampling distribution is an example of a biased statistic.
- ○ True
- ○ False
*Explanation:*
In statistics, when dealing with sampling distributions, the mean of all the sample means is often referred to as the "expected value" of the sample mean. This expected value is equal to the population mean, assuming that sampling is random and unbiased. Therefore, if the sampling is conducted correctly, the mean of the sample means should not be biased.
