Basic large sample CI for the population mean. Samples with-replacement, sample size n “large enough.” claim z table CI

FPC (finite population correction) for sampling without replacement

For sample from a NORMAL population Student-t method For sample from a NORMAL population (in control) valid for each n = 2, 3, … DF (deg freedom) = n - 1 when using t-table t-table

CI for a population proportion p with vs without replacement large n (resp. n, N-n)

CI for the difference of two means (independent samples of n1 resp n2 both large)

CI for the difference of two population proportions (independent samples of n1 resp n2 )
