Physics Full work and explanations, in complete sentences, required for all items. Six student groups working in a science class measure the volume of objects using water displacement. The groups all make six measurements, find the average of their values and report half of the range as the measurements as their uncertainty. The results for the six groups are given below. a) 78.4 + 0.4 cm3 b) 74.2+ 0.9 cm3 c) 77.94 0.7 cm3 d) 74.8 + 0.4 cm3 e) 73.7+ 0.8 cm' f) 78.6 + 0.6 cm3 1) Based on this data how many different objects did the groups work with? 2) Which groups worked on which objects? 3) Which group(s) did the best quality work, i.e., made the best measurements? 4) If another group of students reported a volume of 76.8 + 0.6 cm' for their object, how likely is it that they had the same object as one of the other groups? 5) If the individual measurements were values like 74.3 cm and 78.5 cm', what inference would you draw about the smallest divisions on their graduated cylinders
