The number of steps to cover the same distance was measured for 31 randomly chosen people. The sample mean is = 1440 steps and the sample standard deviation is s = 288 steps. Assume distribution to be normal. Round your answers to the nearest integer (e.g. 9876). a) Construct a 95% two-sided confidence interval on the mean. i b) Construct a 95% lower confidence bound on the mean. i c) Construct a 95% upper confidence bound on the mean.
