In the general population, daily water consumption is normally distributed with a mean of 1,114ml and a standard deviation of 291ml. You wish to examine whether the water consumption of athletes at RMIT is different than the general population. You sampled 29 athletes at RMIT and asked them how much water they consume per day which gave you a mean of 1,412ml and a standard deviation of 311ml. Calculate the lower bound of the 95% confidence interval. Give your answer to 2 decimal places.
