The data below shows the recorded weights, in grams, of a random sample of bananas. Calculate the population mean, mean absolute deviation, and mean absolute deviation to mean ratio. Calculate the mean absolute deviation using the population mean after it is rounded to the nearest tenth. Round to the nearest tenth for all subsequent answers.
39.8, 41.9, 42.8, 38.2, 35.1, 36.2, 37.1, 43.0, 37.8, 32.6, 30.3, 36.9
mean =
mean absolute deviation =
Using those values, the mean absolute deviation to mean ratio =
%
