I also need help with finding the Compute the sample coefficient of variation for each grid (enter your answer to one decimal place)

C @ @ https://www.webassign.net/web/Student/Assignment-Responses/submit?dep=26838694&tags=auto The Hill of Tara in Ireland is a place of great archaeological importance. This region has been occupied by people for more than 4,000 years. Geomagnetic surveys detect subsurface anomalies in the earth's magnetic field. These surveys have led to many significant archaeological discoveries. After collecting data, the next step is to begin a statistical study. The following data measure magnetic susceptibility (centimeter-gram-second x 10-5) on two of the main grids of the Hill of Tara (Reference: Tara: An Archaeological Survey by Conor Newman, Royal Irish Academy, Dublin). Grid E: x variable 27.09 27.09 13.03 26.35 6.00 27.46 18.58 29.31 33.75 29.31 36.71 13.03 20.80 17.84 Grid H: y variable 26.92 27.39 53.71 48.07 42.90 50.89 48.07 15.17 22.69 30.21 39.14 43.84 37.73 50.89 (a) Compute Ex, Ex2, Zy, Ey2.

(Enter your answers to 2 decimal places.) Lower Limit -66.94 X -679.84 X I Upper Limit 113.56 X 756.64 X Use the intervals to compare the magnetic susceptibility on the two grids. Higher numbers indicate higher magnetic susceptibility. However, extreme values, high or low, could mean an anomaly and possible archaeological treasure. Grid H shows a wider 25% range of values. Grid E shows a wider 75% range of values. O Grid E shows a wider 25% range of values. O Grid H shows a wider 75% range of values. X ype here to search O Ei 77OF Polluted air ~ 0 60 ( 4) 7:3 9/12
