Question

The (average) per capita income of a country is $2,200,

a) What is the level of measurement of this value?

b) Does this previous value come from a population whose data is discrete or continuous?

c) True or False. _____ Could exactly the same previous value be obtained by choosing an appropriate random sample?

d) True or False _____ The study that yielded the figure of 22500 for the average income in that country was obtained through an experimental study.

e) True or False _____ The average value obtained from $22500 represents a parameter.

Answer 1

a. The level of measurement of this value = Total National Income / Population of the Country.

b. The data should be discrete in this case because it represents the value of a particular year.

c. False. In choosing a random sample, the value will be close to this value and not exactly equal to this value.

d. True. The experimental study yielded the value of 22500 because under this type of study, the conditions are under the direct control of investigator.

e. False. Since it considers only a sample of value, thus it represents a statistics and not a parameter.
