Consider results of 20 randomly chosen people who have run a marathon. Their times, in minutes, are as follows: 140, 145, 154, 16 166, 177, 186, 193, 197, 203, 215, 222, 236, 241, 254, 261, 270, 280, 282, 287. Calculate a 90% upper confidence bound on the mean time of the race. Assume distribution to be normal. Round your answer to the nearest integer (e.g. 9876).
