Calculate the mean absolute deviation for each possible sample of size 2 from the population Mean Absolute Deviation Sample {9.9) 0 (9,20) 5.5 (9,21) 6 (20,9} 5.5 (20,20} 0 {20,21} 0.5 (21,9) (21,20) {21,21} 0.5 0 (Type integers or decimals rounded to one decimal place as needed.) Calculate the mean of the sample mean absolute deviations The mean of the sample mean absolute deviations is ☐ (Type an integer or decimal rounded to one decimal place as needed.) Calculate the population mean absolute deviation. The population mean absolute deviation is (Type an integer or decimal rounded to one decimal place as needed.) What do these values indicate about a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a population? OA. The sample mean absolute deviation is an unbiased estimator of the population mean absolute deviation because the sample statistic centers around the mean value of the population OB. The sample mean absolute deviation is a biased estimator of the population mean absolute deviation because the sample statistic centers around a different value than the population parameter OC. The sample mean absolute deviation is an unbiased estimator of the population mean absolute deviation because the sample statistic is the same value regardless of which sample is chosen OD. The sample mean absolute deviation is a biased estimator of the population mean absolute deviation because the sample statistic centers around the mean value of the population.

What do these values indicate about a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a population?
OA. The sample mean absolute deviation is an unbiased estimator of the population mean absolute deviation because the sample statistic centers around the mean value of the population.
OB. The sample mean absolute deviation is a biased estimator of the population mean absolute deviation because the sample statistic centers around a different value than the population parameter.
OC. The sample mean absolute deviation is an unbiased estimator of the population mean absolute deviation because the sample statistic is the same value regardless of which sample is chosen.
OD. The sample mean absolute deviation is a biased estimator of the population mean absolute deviation because the sample statistic centers around the mean value of the population.
