Group Members

• Marico Q. Frazier Hendaia Wondim
• Timothy Renfroe Ashley Gaither

Purpose

• To describe mass and volume for each experimental
  item.
• To estimate the relationship between mass and
  volume.
• To compare experimental and accepted density
  values.

4
Methods

• Measure the mass of the right cylinder and the
  rectangle cube
• Measure to find the radius of the cylinder and
  its height to find its volume
• Measure to find the length, width, and height of
  the rectangle cube to find its volume
• Divide the mass of each object by its volume to
  find the experimental density

Hypothesis

• Null Hypothesis Experimental Accepted
  Densities are same.
• Alternative Hypothesis Experimental Accepted
  Densities are different.

12
Paired t-test
P-value gt 0.05. So, failed to reject null
hypothesis.
13
Conclusion

• Since we failed to reject null hypothesis, the
  experimental density supports the accepted
  density. Thus, we confirm the formula, Density
  Mass / Volume.
