The tolerable deviation rate (TDR) has a significant effect on sample size. The relationship of TDR to sample size is:
A) direct (larger TDR = larger sample).
B) not determinable.
C) inverse (larger TDR = smaller sample).
D) variable (sometimes larger, sometimes smaller).

When the tolerable deviation rate (TDR) is increased, the sample size required to achieve a given level of precision decreases. This is because a higher TDR implies greater variability in the population, and therefore a smaller sample can still yield accurate results. Conversely, a lower TDR requires a larger sample size to achieve the same level of precision, as smaller variability in the population necessitates a larger sample to capture it. Therefore, the relationship between TDR and sample size is inverse.
