Multiple Choice

A science instructor assigns a group of students to investigate the relationship between the pH of the water of a river and its water's hardness (measured in grains) .Some students wrote these conclusions: "there was a very strong correlation of 0.902 grains between pH of the water and water's hardness." Is the calculation of the correlation appropriate?

• A)No: there is little or no association.
• B)Yes: the pH and the hardness of the water are data collected from the same river.
• C)No: pH and hardness of water have different units.
• D)Yes: correlation is less than 1.
• E)No: correlation has no units.
