When testing μ, how do we decide whether to use the standard normal distribution or a student's t distribution? if the x distribution is normal and n ≥ 30 with known σ we use the student's t. with the same conditions and unknown σ we use the standard normal. if the x distribution is normal and n ≥ 20 with known σ we use the standard normal. with the same conditions and unknown σ we use the student's t. if the x distribution is normal and n ≥ 30 with known σ we use the standard normal. with the same conditions and unknown σ we use the student's t. whenever we assume the populations are independent, we always use the standard normal.
