BQA 2113 Exam 3 Questions with
Complete Solutions
The Central Limit Theorem is considered to be one of the most important ideas in
statistics
The CLT requires random, large samples
The target parameter we are interested in estimating in statistics is often unknown
What could be a possible target parameter?
-s
-μ
- s^2
- x̄ μ
A point estimator is an estimate of the target parameter
, True or False: The reliability of a point estimate is often found by obtaining the interval
estimator. true
True or False: A point estimate is always at least two numbers. false
True or False: The interval estimator is the same as the confidence interval. true
True or False: A confidence interval is a formula. true
True or False: Confidence intervals use sample information to calculate a range that contains the
target parameter. true
If the population is normal, when determining if to use the Z table, the sample size
doesn't matter
The standard error of the mean is represented by σ(subscript x̄)
