Question 132473: 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?

consulting a Z-table shows that the bottom 10% is beyond 1.2816 standard deviations from the mean

so the cutoff weight is 25-4(1.2816)
