Question 2 0 l 0 Pts An experiment subject only to random uctuation within a normal distribution collects the following set of unitless numerical values: 15.8, 17.8, 19.5, 20.0, 14.7,16.6,16.8,19.4, 18.3 A number of hypotheses are put forward for the theoretical value of what is measured here. Select all of the theoretical values given below that can be ruled out by our usual 1-sigma uncertainty criterion. 15.6 15.9 19.5 19.7 None of these theoretical values is conrmed by this data. ect Question 1 0 / 0 pts The gure below shows the efforts of a lab group. They made four marble drops, and then correctly followed the procedure to determine the average landing point, which is designated by the red star. Then someone accidentally dropped a marble on the paper, making a fth dot. Which dot is the result of this accident? A reasonable amount of precision may be needed to answer this question, so you may want to capture this diagram and print it out, allowing you to work with it more easily
