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.
Typical Costs. The cost for installation of a hardwood floor is usually quoted on a per-square-foot basis. The total cost of a given floor can vary greatly depending on the cost of the flooring material you choose and your location, but you can expect the range to be between $5 and $10 per square foot.
