Question

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

Answer 1

From the given boxplot:

a) For Site 1:

Least = 25

Greatest = 110

For Site 2:

Least = 20

Greatest = 125

b) Distribution of Site 1: Option D

Distribution of Site 2: Option C

c) Option A
