OPTIONS
- Any sample size, if randomly selected, can be suitable for analysis. Since it is sampling, it is not expected to have a specific number of samples.
- 10% of the total
- One sample every hour
- Determine sample size using formula and base it on the tolerance and confidence interval expected and standard deviation or the current error rate of the population
ANSWER
