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.
Hardwood floors have two main costs. The cost of the flooring, which ranges from about $4.50 per square foot and up. The cost of labor which typically runs between $3.00 to $5 â¦ .00 per square foot. There will be added costs if the contractor has to tear up an old floor.  So measure the room dimensions.hen multiply by some reasonable number for the wood price & labor. Say $5.00 per sqft for flooring and $4.00 per sqft for labor = $9.00 per sqft total. Then this job should cost about $9 x 300 = $2700.
