2. I have data sets (measurements) and I need to know if values are normally distributed. I would like to get this information programmatically in my application and not via plotting and checking it visually myself.
1 Installing a standard solid-strip hardwood floor averages about $8 a square foot for materials, insulation and site finishing, and up to $12 a square foot for wide pine planks, or $1,150-$1,750 for a 12x12-foot room.
A more skilled wood to install, a professional might charge $2-$6 per square foot for installation. Hardwood: With a great variance of wood types and colors, hardwood flooring can cost $2-$14 per square foot or more, depending on how solid the planks are, thickness, finish, and how exotic the wood is.
