20.0/25.0 points (graded) We first look at the smoothed precipitation data (PRCP_520) for the state of Washington. Which of these statements are valid interpretations of the PCA analysis of the smoothed precipitation data for the state of Washington? l:l Precipitation generally happens in the summer season (June - August) lZl Precipitation generally occurs in the winter season (December - February) * l:l The second eigenvector for this data represents the deviation in the yearly rainfall for a particular station from the mean rainfall across all stations in Washington and all years in the dataset. l:l A positive value for the coefficient associated with the second eigenvector implies that the rainfall was heavier than the statewide average across the entire dataset
