⦁ The table shows the soil density of several soil samples at different depths.
⦁ Depth (m) ⦁ 1 ⦁ 4 ⦁ 6 ⦁ 7 ⦁ 10 ⦁ 13 ⦁ 14 ⦁ 21 ⦁ 23 ⦁ 26 ⦁ 28
⦁ Soil density ( ) ⦁ 1040 ⦁ 1068 ⦁ 1122 ⦁ 1180 ⦁ 1201 ⦁ 1252 ⦁ 1269 ⦁ 1274 ⦁ 1255 ⦁ 1278 ⦁ 1293
⦁ .
⦁ Use the equation to estimate the soil density of a sample at a depth of 20m. Write the quadratic regression equation that models the data. Let x = depth below the surface and let y = soil density. Show your work.
