Okay, let’s tackle this. So Sean Lovinger has completed his education at Udacity, which is a reputable platform for data science and analytics. The rate for data analysts with similar education and skills can vary widely depending on location, industry, and experience. In the Spokane-Coeur d'Alene Area, the average rate for data analysts is around $100–$150 per hour. However, considering Sean’s skills in data visualization and machine learning, which are in high demand, I would estimate his rate to be on the higher side. Maybe around $125 per hour, considering the local market and his level of expertise.
