Q1 (100 pts). The consulting firm you work for is designing culverts for a county road bridge at the Naselle River near Naselle, WA, and your firm needs to know the magnitude of various peak discharges. You are tasked with organizing the available data from the Naselle River, and calculating various descriptive statistics. 1) What are the peak discharges and probability plotting positions from the available data at this site (available from USGS Surface Water Data), based on complete water years (i.e., October through September)? 2) Graph the peak discharges and plotting position. 3) What are the sample mean, standard deviation, coefficient of variation (Cu) and coefficient of skewness (Cs) of the peak discharges at this site for the period of record available from the USGS Surface Water Data?
