Often the raw data itself is not normally distributed, but the logarithm of the data may in fact be a normally distributed set. To test if your numbers are log-normal, take the logarithm of each point, then apply one or all of the tests above.
Because labor costs vary across the country, the cost of adding Hardie board siding to a home depends on location. The Bureau of Labor Statistics show that as of May 2010, installers made a mean $21.10 per hour, with lows of $11.85 and highs of $34.45.
I am having new granite countertops installed tomorrow!! I hired the same company to install basic 4 tumbled tavertine tiles on the diagonal for the backsplash. I am starting to question the labor cost for installing the backsplash. I have 35 sq. feet of backsplash. The total for the labor is $844.He said the basic install price is $9/sq. ft. for backsplash tiles. Plus extra for the diagonal.Plus extra money for the sealer etc. When I divide the total labor of $844 by 35 sq. ft., I get about $25/sq. feet for just the labor without the tiles. This does include the extra charge for diagonal and for the sealers. have 35 sq. feet of backsplash. The total for the labor is $844. He said the basic install price is $9/sq. ft. for backsplash tiles. Plus extra for the diagonal.
