Here is my question!

I 4.37 (Page 127): 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 condence level of 95% of the mean value of the whole batch of perfume from which the 10 samples were taken
