An unknown metal has been found and the following experimental results have been tabulated in the table below. The table contains the grams of the unknown metal and the volume in milliliters of water displacement. Find a linear model that expressesmass as a function of thevolume.

grams	Volume in ml
18	188.8
19.5	200.5
21	218.1
22.5	231.3
24	246.7
25.5	267.5
27	288.9

A) Write the linear regression equation for the data in the chart.


Volume =__?__  x + __?__ where x is the grams of the unknown metal.
Round your answers to 3 decimal places

B)  If the mass of an unknown metal is 16, using your un-ounded regression equation find its predicted volume.  Round your answer to 1 decimal place.   __?__ mL
