Suppose that the weights of 10-week old kittens follow a normal distribution, with a mean value of 25 ounces and a standard deviation of 4 ounces. If a kitten’s weight is in the bottom 10% of the distribution of weights, then it is said to be undernourished. What is the cutoff weight for an undernourished kitten?
\n" ); document.write( "------------------------
\n" ); document.write( "mean = 25 oz
\n" ); document.write( "sigma = 4 oz
\n" ); document.write( "----------------
\n" ); document.write( "Find the z-value at 10% in your z-chart or using InVNorm(0.1)
\n" ); document.write( "InVNorm(0.1) = -1.28155...
\n" ); document.write( "-------------
\n" ); document.write( "Find the corresponding raw score value:
\n" ); document.write( "z = (x - mu)/sigma
\n" ); document.write( "x = z*sigma + mu
\n" ); document.write( "x = -1.28155*4 + 25
\n" ); document.write( "x = 19.87379... (kittens weighing less than 19.8739 oz are undernourished)
