OFFICIAL QUESTIONS WITH ANSWERS.
1. Standard deviation - correct answer -the square root of the
variance and provides a measure of the standard, or average,
distance from the mean
2. Three concepts that a statistical inference problem contains -
correct answer -the population, the sample, and the statistical
inference
3. Parameter - correct answer -a descriptive measure of a
population
4. Statistic - correct answer -a number that describes a sample
5. Statistical inference - correct answer -process of making an
estimate, prediction, or decision about a population based on a
sample

6. Confidence level - correct answer -Proportion of times that an
estimating procedure will be correct
7. Confidence level + significance level - correct answer -= 1
8. Simple random sampling - correct answer -A sampling
procedure in which each member of the population has an
equal probability of being included in the sample. (example -
tickets in a bin each assigned a number)
9. Stratified random sampling - correct answer -obtained by
separating the population into mutually exclusive sets of data
(strata) then drawing a simple random sample from each
stratum
10. Cluster sampling - correct answer -random sample of the
groups or clusters of elements versus a simple random sample
of individual objects
