In a recent survey in a dorm for first year girl students indicate that 62 percent like the chocolate ice cream rather than other flavours. Suppose we select a sample of fouteen people and ask them to give their choice of ice cream. Find the mean, variance and standard deviation of the sample. ( d.p. means decimal places)
