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 their values b. group: 3rd and 4th hours, with values under the true density group: 1st, 2nd, 5th, and 6th hours, with values over the true density c. group: 3rd hour, with a 1 value group: 4th hour, with a 2 value group: 1st and 2nd hours, with 3 values group: 5th and 6th hours, with 4 values d. group all classes as accurate
