The Tribune claims that the time of travel from downtown to the University via the bus has an average of µ = 27 minutes. A student who normally takes this bus believes that µ is greater than 27 minutes. A sample of six ride times taken to test the hypothesis of interest gave a mean of 27.5 minutes and standard deviation of 2.43 minutes. The value of the test statistic for testing this hypothesis is
 0.532
0.460
0.504
0.460
0.504
