### Exploring Linear Relationships through Water Displacement**Experimental Objective:**An unknown metal has been discovered, and the following experimental data have been recorded to understand the relationship between the mass of the metal (in grams) and the volume of water displaced (in milliliters). A linear model is sought to express mass as a function of volume.**Experimental Data:**The table below encapsulates the measurements collected during the experiment:| Grams (g) | Volume (mL) ||-----------|-------------|| 19 | 258.3 || 21.5 | 286.4 || 24 | 323 || 26.5 | 363.8 || 29 | 386.3 || 31.5 | 436.7 || 34 | 457.5 |**Task A: Determining the Linear Regression Equation**- To find the linear regression equation that best fits the data, denote \( x \) as grams of the unknown metal.- The volume \( V \) is expressed as: \[ V = mx + b \]- Here, \( m \) and \( b \) are constants calculated through regression analysis.**Task B: Predicting Volume for a Given Mass**- Using the regression equation derived in Task A, a specific application involves predicting the volume displaced when the mass of the unknown metal is 17 grams.- Ensure to use the unrounded regression coefficients for accuracy and round the final predicted volume to one decimal place.This analysis helps understand the quantitative relationship between mass and volume displacement in metals and is fundamental in material science and engineering applications.
