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.
the cost of a hardwood floor can vary greatly depending on the type of wood you choose because a well finished hardwood floor requires careful craftsmanship and a relatively large amount of labor the overall cost of a flooring project is divided almost equally between labor and material costslooring that s in good condition will be easier to refinish than excessively worn or damaged flooring so expect the labor cost to be between $ 1 and $ 3 per square foot depending on the state of your current floor
