Assume that cans are filled so that the actual amounts have a mean of 13.00 ounces. A random sample of 36 cans has a mean amount of 13.86 ounces. The distribution of sample means of size 36 is normal with an assumed mean of 13.00 ounces and a standard deviation of 0.09 ounce. a. How many standard deviations is the sample mean from the mean of the distribution of sample means? standard deviations (Round to the nearest tenth as needed.

Solution

SD = 0.09 / sqrt(36) = 0.09 / 6 = 0.03 / 2 = 0.015 ~ 0.02 Answer
