Assume that cans of cola are filled such that the actual amounts have a population mean of u 16.00 ounces. A random sample of 49 cans has a mean amount of 16.44 ounces. The distribution of sample means of size n=49 is normal with an assumed mean of 16.00 ounces, and those sample means have a standard deviation of 0.05 ounce. 

How many standard deviations is the sample mean away from the mean of the distribution of sample means?
