Question

Response Questions Part A To B Oysters are categorized for retail as small, medium, or large based on their volume. he grading process is slow and expensive when done by hand. A computer program estimates oyster volume based on the pixel area of two-dimensional (2D) images of the oysters. The given table shows the actual volume (in cm3) and 2D reconstruction (in thousands of pixels) for 30 oysters 2D (thousand pixels) 2D 2D 3D (million Actual voxels) (cm3) Actual 3D (million 2D (million Actual (thousandvoxels)(cm*) 3(thousand voxels) 13.0447.9075.136699 10.53 31.216 3.94278310.9537.156 4.707532 29.070 3.019077 24.5902.768160 35.343 3.527926 13.2148.0824.945743 32.118 3.138463 15.5948.070 5.728880 40.976 4.01399211.38 45.12 4.4107917 2237.020 4.558251 39.3333.449867 22.8951.928109 13.7551.35 5.609681 5.292105 cm pixels) pixels) 741.458 4.7951510.84 41.852 4.0526387.97 17.4260.891 6.45311513.12 44.608 5.3345587.3-4 7.2329.9492.895239 8.48 10.0341.616 3.67274614.2447.4815.6796367.83 9.94 7.53 12.7352.712 5.4815455.67 12.6641.5005.0167628.26 34.717 3.987582 15.35 65.361 5.565995 1 27.320 2.678423 15.44 50.910 6.303198 9.25 34.804 3.450164 14.3753.281 Engineers were given the task to improve on the 2D reconstruction software. Thev designed a new program that estimates ovster volume using three- dimensional (3D ) image processing. Ihe table gives the actual volume, in cm of 30 oysters and the 3D volume reconstruction, in millions of volume pixels A. Use the regression equation to 3 decimal places to predict the actual volume of an oyster with a 3D reconstruction of 4.5 million volume pixels to one decimal place. (Enter your answer rounded to one decimal lace B. What is the percentage of the observed variation in actual oyster volume explained by this regression line? (Enter your answer rounded to the nearest whole number.)
