The volume contained in each of a sample of 10 bottles of expensive perfume is

measured. If the mean volume of the sample measurements is 100.5 ml with a standard deviation of 0.64 ml, calculate the upper and lower bounds to a confidence level

of 95% of the mean value of the whole batch of perfume from which the 10 samples

were taken.
