Find the Mean, Median, Mode and Midrange for the following set of data. Round answers to two decimal places when needed. If one of these does not exist write NONE in the answer. US Median age of different ethnic groups Census Group White Black Native American Asian Hawaiian/Pacific Islander Other Median Age 39.8 31.8 31.4 34.3 28.3 28.6 (Data comes from https://factfinder.census.gov/faces/tableservices/jsf/pages/productview.xhtml? pid=ACS_16_1YR_S0201&prodType=table) Mean = Median = 31.6 Mode = NONE Midrange = 34.05
