    To obtain the standard error of the sample mean, we need to know the standard deviation of the sample.
    The standard error of the sample mean is always larger than the standard deviation of a sample
    The standard deviation of a sample measures how spread the observations in the sample are relative to the sample mean.

  • Q2
    Which of the following statements is INCORRECT?

    If a value outside a 95% confidence interval is used as an estimate for the population mean, the chance that we are correct is 95%
    Confidence interval provides an interval that captures the population mean with a given probability
    A 95% confidence interval extends from the sample mean minus the margin of error to the sample mean plus the margin of error.
