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.

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

Working Hard Finding an Answer

Measurements Volume = Length * Width * Height

Descriptive Statistics Graphical Method

Density Density = Mass / Volume

Descriptive Statistics Numerical Method

Linear Regression without intercept term

Hypothesis Null Hypothesis: Experimental & Accepted Densities are same. Alternative Hypothesis: Experimental & Accepted Densities are different.

Paired t-test P-value > So, failed to reject null hypothesis.

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