In archaeology, the depth (below surface grade) at which artifacts are found is different archseological perlod. The figure below sites are from similar geographic locations. Notice that the stems are in the center of the d stem, while the leaves for Site II are to the right of the stem. t very is a back-to-back stem plot showing the depths of artifact locations important. Greater depths sometimes indicate older artifacts, perhaps from a at two different archaeological sites. These are in the center of the diagram. The leaves for Site I artifact depths are shown to the left of the 1210 25om at She 1and 20 cm at Site Ste l 5555 4 0005 50 S 005 555$500 5000 sso0 9 5 5 10 (a) What are the least and greatest depths of artifact finds at Site 1? Least cm Greatest What are the least and greatest depths of artifact finds at Site I Least Greatest om (b) Describe the data distribution of depths of artifact finds at Site I fairly uniform in shape except for a gap O strongly skewed to the right O fairly symmetric, centered near 90 cm O fairly symmetric, centered near 70 cm Describe the data distribution of depths of artifact finds at Site II fairly uniform in shape except for a gap fairly symmetric, centered near 90 cm O strongly skewed to the right falrly symmetric, centered near 70 cm strongly skewed to the right O fairly symmetric, centered near 70 cm I, there is a gap in the depths at which artifacts were found. Does the Site I data distribution suggest that there might have been a period of Yes, it would appear that Site II probably was unoccupied during the time period associated with 70 to 100 cm Yes, it would appear that Site II probably was unoccupied during the time period associated with 50 to 80 cm. () At Site no occupation? Yes, it would appear that Site II probably was unoccupied during the time period associated with 100 to 120 cm. No, the distribution suggests that the area was likely occupied at all times.
