Sir population standard deviation eka danne netiva habei sample size larger than 30 nam Z distribution ekada use karanne

[@RS-hs6ni]

Population එකේ සලකන variable එක normally distributed නම්, sample size එක 30 ට අඩු වුනත් අපිට Z distribution එක use කරන්න පුලුවන් නේද?

[@statsenaka2894]

when population standard deviation is not known and sample size is small, then t can be used.
