User question:
user: I'm currently working on a financial report and I need to crunch some numbers. First, could you calculate the standard deviation for the data set [23, 436, 1231, 123]? Also, I'm helping a friend figure out potential housing costs; they're looking at a 30-year mortgage on a $350,000 loan with a 3.5% interest rate. What would their monthly payment be? Lastly, I'm planning a trip to San Francisco and I need the GPS coordinates for navigation purposes. Can you provide me with the latitude and longitude of San Francisco?
