A statistician had a data set containing 13 whole numbers written in his research notebook. He spilled coffee on his notebook and now he cannot read two of the data values. He remembers that the sample mean of the original data was 30.077 and the sample medium was 29. Use your power of deduction and the eleven still reliable data values given below, to determine the range of possible values for the two lost data points. 22,41,19,50,23,15,47,11,35,37,44

Show that [frac{d}{dt}int_{-infty}^{infty} Psi_{1}^{*}Psi_{2}dx = 0] for any two normalizable solutions to the Schrödinger equation, (Psi_{1}) and (Psi_{2}), for the same potential (V(x)). Why wouldn't this be true if they were solutions for different potentials? (Hint: For the proof, integration by parts may come in handy. For the second part, you shouldn't have to do any more math, just point to the part in your proof that would change.)

Suppose that the known value of the initial speed is 5.57m/s. if you experimentally find the value of initial speed as 7 m/s, find the percent error of your experimental value. (Give your answer as integer, and don't type % sign, for example, to express 60% only write 60)
