Question Answered step-by-step Please read and answer questions below: Data gathering and analysis… Please read and answer questions below: Data gathering and analysis are an important part of the scientific method because data are critical for testing hypotheses.  One example of data gathered by forensic anthropologists is the measuring of skeletal elements to help build the osteobiography of a person (age, sex, stature, etc).  The graph below shows how such data can be analyzed, to further provide useful information for forensic anthropologists and law enforcement.  Each diamond is a data point that represents an individual whose femur length and height is known, and these data points were used to generate the equation and the R2 value.   We didn’t cover this in class and you are not responsible for knowing the math, but the equation in the top right describes the slope of the black line.  The R2 value describes how well the two variables are correlated with each other, and I will tell you that .802 is a very strong correlation.   This tells us that femur (thigh bone) length is correlated with the height of a person, so much so that if we only have a single individual femur, that can be used to PREDICT the height of the person it belonged to. Image transcription textHeight v Femur Length V = 4.428x + 49.52 R- = 0.802 200 190 180 Height of person (cm) 170 160 150 140 2025 30 35 40 Length of femur (cm)… Show more12. a) what the graph is showingb) why this information is useful for forensic anthropologists 13. How tall (in cms) was the person whose femur measured 30 cm in length? 14. Part of a skeleton was found in your friend’s closet.  The femur measures 43.8 cm. Another of your friends, who mysteriously went missing a few months ago, was 188 cm tall.  Could the femur in the closet be that of your missing friend?  How do you know? 15. Another friend of yours, who’s rather stuck-up, brags that her legs are proportionally longer than those of most other people.  She is 170 cm tall, and her femur measures 41.0 cm in length.  Is she right in that her femur is longer than expected?  How can you tell?  Math Statistics and Probability ASM 275 Share QuestionEmailCopy link Comments (0)

Both found this helpful as they had previously only used a Doona at home. At lunch Sally and Elaine talked about their experiences and Sally confided that she was struggling sometimes to understand the language being used. Elaine showed Sally how she had written down some words and abbreviations in her notebook to help her remember. After lunch Elaine and Sally returned to the ward area and were buddied up with John. John had been an enrolled nurse for the last three years and was keen to assist Elaine and Sally to settle into the ward. John showed Elaine and Sally the 'steri' room and the pan room or 'dirty' room and explained what was kept in each area and why items were kept separated.
