True
Observational forms and questionnaires require adequate pretesting.
True
Systematic sources of error do have an adverse impact on reliability because they affect the measurement in a constant way and do not lead to inconsistency.

When determining the sample size, if the population standard deviation, σ is unknown and an estimate is used, the standard deviation should be re-estimated once the sample has been drawn. Next a revised confidence interval should be calculated to determine the precision level actually obtained.
True
When the sample size is 10 percent or more of the population size, the standard error formulas will overestimate the standard deviation of the population mean or proportion. Hence, these should be adjusted by a finite population correction factor.
