3. Current population survey. The employment status (employed or unemployed) of each individual in the U. S. workforce is a set of data that is of interest to economists, businesspeople, and sociologists.
To obtain information about the employment status of the workforce, the U. S. Bureau of the Census
conducts what is known as the Current Population Survey. Each month interviewers visit about 50,000
of the 117 million households in the United States and question the occupants over 14 years of age
about their employment status. Their responses enable the Bureau of the Census to estimate the
percentage of people in the labor force who are unemployed (the unemployment
rate)
a) Define the population of interest to the Census Bureau.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
