1. Using the data file used previously, make a histogram of the number of muons passing through the muon detector per second. You can limit the displayed histogram to be between 0 and 18, inclusive. Remember that the data records are recorded every second and that for any record whose first value is 40,000 or above, the amount that exceeds 40,000 tells you how many muons per second passed completely though the dector. For example, 400002 means 2 muons passed throiuhg the detector in the second described by the secod integer of the same data record. Ignore records whoe first integer is below 40,000. You worked already on this task in class. 2. Now fit this histogram withal a poisson distriibution taking care to fit to the center of the bins as described in class. Your plot should contain the histogram, data points and a curve through the the data points. Determine the value (lambda) from the fit and its corresponding uncertainty. For our poisson distribution, lambda tells you the mean number of passing muons per second. 3. Calculate 200-230 prime numbers starting from 3. Plot the the values of the primes as a function of their ordinal number. For example, th prime 3 corresponds to 1, 5 to 2, 7 to 3, and so on. You can use your own code or a built-in method to determine the primes. Place the primes in an array and print the array so we can verify you did the calculation correctly. DO NOT print out the primes line by line or your pdf will be a mile long. 4. Plot the primes as a function of their ordinal number. For example, th prime 3 corresponds to 1, 5 to 2, 7 to 3, and so on. This plot will have a curvatue to it. Fit the plot with a line, a quadratic and a cubic. What are the vales of each paramter in those cruves and their uncertainties? What do you think is the best fit, accounting foruncertainty and simplicity of the curve?
