| 1. | Since each observation has expectation ? so does this sample mean.
|
| 2. | In exponentially-weighted moving average of all prior sample means.
|
| 3. | Where \ overline { X } is the sample mean.
|
| 4. | An alternative to the sample mean is the sample median.
|
| 5. | If the sample mean and uncorrected sample variance are defined as
|
| 6. | Where \ overline { x } is the sample mean.
|
| 7. | A sample mean is often a good estimate of the population mean.
|
| 8. | The Newman Keuls method employs a stepwise approach when comparing sample means.
|
| 9. | Population 3 is the sampling distribution of the sampling mean.
|
| 10. | The mean of all possible sample means is equal to the population mean.
