If p-value is smaller than‚ then we reject H0‚ which means the mean driving distances of current balls and new balls are different. 2. From the t distribution table we find that p-value is between 0.05 and 0

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine
