Group of answer choices We would do a t-procedure because we have the standard deviation. We would do a t-procedure because the sample size is large. We would do a t-procedure because we do not have the population standard deviation and the sample size is small. We would do a z-procedure because we have the standard deviation. We would do a z-procedure because we do not have the population standard deviation and the sample size is small.
