QMB Exam 1 Review
Parameters are: - Answer-numerical characteristics of a population
The medical doctor of a company looks at medical records of all 50 employees and finds the mean
systolic blood pressure for these employees is 126.07. The value of 126.07 is: - Answer-A parameter
(the value of 126.07 is a parameter because it describes the population.)
Which of the following is not a symbol for a parameter?
a. p
b. σ
c. µ
d. s - Answer-s
The distribution of values taken by a static in all possible samples of the same size from the dame
population is the sampling distribution of: - Answer-a sample
The central limit theorem states that: - Answer-if the sample size n is large and if the population is
normal, then the sampling distribution of the sample mean can be approximated by a normal
distribution.
