1. The following does NOT hold true for t distribution?
- Confidence interval will be wider than for large samples.
- Region of acceptance will be wider than for large samples.
- Larger computed t value will be needed to reject the null hypothesis than for large samples using z.
- There is only one t distribution.
- None of the above
