3. The mean volume of draught beer served in pint glasses in a particular pub is known to be 0.564 litres. A consumer organization takes a random sample of 64 pints of draught beer and finds that the standard deviation of this sample is 0.025 litres. What is the probability that the mean volume of the sample will be more than a pint (0.564 litres)?
