True or false a t-statistic estimates the standard error by

Reference no: EM13629714

1) TRUE OR FALSE: A t-statistic estimates the standard error by using the sample variance to approximate the population variance.

2) TRUE OR FALSE: A t-distribution with infinite degrees of freedom is a z-distribution.

3) TRUE OR FALSE: As the degrees of freedom for a t-test increase, the critical values for that test also increase.

4) TRUE OR FALSE: The repeated measures design, but not the matched-pairs design, is associated with greater power to detect an effect compared with the independent samples design.
