Question
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate.
Ages of survey respondents.
A) Ratio
B) Ordinal
C) Nominal
Determine whether the given description corresponds to an observational study or an experiment.
4) A doctor induces a cardiac stress test to determine the reason for a patient's illness.
A) Observational study
B) Experiment
D) Interval
Provide an appropriate response.
5) A computer company employs 100 software engineers and 100 hardware engineers. The personnel manager
randomly selects 20 of the software engineers and 20 of the hardware engineers and questions them about career
opportunities within the company. Does this sampling plan result in a random sample? Simple random sample?
Explain.
A) Yes; yes. The sample is random because all employees have the same chance of being selected. It is a simple
random sample because all samples of size 40 have the same chance of being selected.
B) No; no. The sample is not random because not all employees have the same chance of being selected. It is not
a simple random sample because some samples are not possible, such as a sample consisting of 30 software
engineers and 10 hardware engineers.
C) Yes; no. The sample is random because all employees have the same chance of being selected. It is not a
simple random sample because some samples are not possible, such as a sample consisting of 30 software
engineers and 10 hardware engineers.
D) No; yes. The sample is not random because not all employees have the same chance of being selected. It is a
simple random sample because all samples of size 40 have the same chance of being selected.
