Answer

Explanation:

Step1: Analyze data - patterns

Check if data on mass - volume measurements of unknown solids shows consistent trends like a direct proportion. For example, if doubling the volume doubles the mass, it may support a density - related hypothesis.

Step2: Evaluate hypothesis support

If the pattern is clear and repeatable across different samples of the unknown solid, it supports the hypothesis. If not, it fails to support it. For instance, if some samples have erratic mass - volume ratios, the hypothesis is not supported.

Step3: Consider precision of measurements

Precise measurements with the graduated cylinder are crucial. Using multiple measurements and averaging can increase precision. One measurement may have random errors.

Step4: Determine significant figures

Measurements from the graduated cylinder should be reported with the correct number of significant figures based on its precision. For example, if it can measure to 0.1 mL, the volume should be reported accordingly.

Answer:

The data support or fail to support the hypothesis depending on the consistency of the mass - volume patterns. Precise measurements using a graduated cylinder and correct reporting of significant figures are important for accurate determination of the properties of the unknown solid.
