The precision of an estimate is affected by three factors:
A) population variance, sampling technique, and sample standard deviation.
B) sample size, population variance, and location of participants.
C) population variance, sampling technique, and sample size.
D) population mean, population standard deviation, and population variance.

The precision of an estimate is affected by the population variance (as this affects the amount of variability in the population), sampling technique (as this affects how representative the sample is of the population), and sample size (as larger samples tend to produce more precise estimates). Sample standard deviation and location of participants may also impact precision, but they are not the three primary factors listed. Similarly, population mean, population standard deviation, and population variance are all characteristics of the population, but they are not necessarily factors that directly impact the precision of an estimate.
