Document Summary

Student: __________________________________________________________________________: a population is a set of existing units. (cid:10) If we examine some of the population measurements, we are conducting a census of the population. (cid:10) True(cid:160) (cid:160) false: a random sample is selected so that on each selection from the population every unit remaining in the population has an equal chance of being chosen. (cid:10) True(cid:160) (cid:160) false: a process is in statistical control if it does not exhibit any unusual variations. (cid:10) True(cid:160) (cid:160) false: an example of a quantitative variable is the make of a car. (cid:10) True(cid:160) (cid:160) false: an example of a qualitative variable is the fuel efficiency of a car. (cid:10) True(cid:160) (cid:160) false: statistical inference is the science of using a sample of measurements to make generalization about the important aspects of a population of measurements. (cid:10) If we sample without replacement, we do not place the unit chosen on a particular selection back into the population. (cid:10)
