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 footlooring 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
