An analysis of archaeological ruins at a site on the Greek island of Panarea recorded the total floor area (square meters) of prehistoric huts used as dwellings and prehistoric huts used for utilitarian functions. The square footage data for these huts is given in the table below: Dwelling: 18.5 19. 19.5 18.5 19.5 19. 18.5 17. 18.5 15.5 16.5 17. 20.5 18.5 Utilitarian: 18.5 19. 15. 17.5 18. 15.5 17.5 15.5 16. 16.5 16. 16. 18.5 15. Using two-decimal place accuracy, the mean square footage for the utilitarian huts sample is Question Blank 1 of 6 . The standard deviation of the utilitarian huts sample is Question Blank 2 of 6 . The standard deviation of the dwellings hut sample is Question Blank 3 of 6 . The first quartile of the dwellings hut sample is Question Blank 4 of 6 . The median of the dwellings hut sample is . The third quartile of the dwellings hut sample is
