You are a data scientist for the National Weather Service. Usually, you are analyzing weather data, but today something has gone wrong with one of two remote weather stations that transmit their data over radio frequencies to the headquarters. One of the stations has stopped responding! What happened? Zombie apocalypse? Alien invaders? Sentient robot unicorns? Maybe, but its probably just a blown power relay. These stations are pretty far away, so your boss doesnt want to waste time sending a repair crew to both stations. Before your boss has time to brief the repair team on which station went silent, she is called away to an urgent meeting! Oh, no! The repair crew doesnt know which station to go to. Being a clever data scientist, you suggest that we look at the radio transmission data and see which radio frequency isnt transmitting a signal and which one is. This is your task! On the class data website, youll find a CSV file for Challenge 1 that has three columns: transmission time in milliseconds, signal amplitude, and FM radio frequency in kHz. You must first find out which radio frequency is generating a structured signal and which is just random noise. Once youve found the correct frequency, then do a scatter plot of the data that was transmitted. Finally, youll need to draw a line plot of the mean amplitude for each unit time on top of the scatter plot. using python
