I have a new hobby - a saltwater fish tank that will contain mostly live corals (called a reef tank). As part of the planning stage, I reached out to 500 experienced Central Florida reefers (people who currently have a reef tank) and asked them to provide the following information: Size of the tank (in gallons), and Type of Lighting used (T5, LED, or Hybrid). In my sample 380 used LED lighting, 75 used hybrid lighting, and 45 used T5 lighting. A recent article on the Reef2Reef forum indicated that the percentages in each of the lighting categories was the same.To check this statement, what type of analysis should I run?
