Mr. Potter’s physical science classes conducted an experiment to determine the density of aluminum. Here are the density values each class period came up with: 1st hour = 3.1 g/ml, 2nd hour = 3.05 g/ml, 3rd hour = 1.9 g/ml, 4th hour = 2.35 g/ml, 5th hour = 4.2 g/ml, and 6th hour = 4.0 g/ml. If Aluminum’s true density is 2.7 g/ml, how would you group the class values based on accuracy?
a.
Group: 1st, 3rd, 5th, and 6th hours, with one recorded decimal place in their values
Group: 2nd and 4th hours, with two recorded decimal places in
