How can a simple random sample be selected using a random number table?

• By selecting three digits from the table that are less than the total number of accounts

• By selecting three digits from the table that are greater than the total number of accounts

• By selecting three digits from the table that are equal to the total number of accounts

• By selecting any consecutive three digits from the table

What is the sampling distribution of the sample mean?

• The probability distribution that describes the distribution of the sample means

• A sample that overrepresents or underrepresents some segment(s) of the population

• A single-valued estimate, calculated from the sample data, which is intended to be close to the true population value

• A list which identifies all members of the population

What is a point estimator?

• A list which identifies all members of the population

• The probability distribution that describes the distribution of the sample means

• A single-valued estimate, calculated from the sample data, which is intended to be close to the true population value

• A sample that overrepresents or underrepresents some segment(s) of the population
