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 labor costs for hardwood floors range from $6 to $8 per square foot, although some costs could go as high as $10 or $12 per square foot if this is a difficult installation. Maintenance. For most hardwoods, the maintenance is the same regardless of size, finish, or wood species.
