Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.05 level of significance, that the mean travel times of the two routes are different? Perform a two-tailed test. Then fill in the table below. Carry your internmediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: 合 The alternative hynothesis: ロ=ロ Degrees of freedom: 16 The type of test statistic: The value of the test statistic: (Round to at least three decimal places.) -1.274 The p-value: (Round to at least three decimal places.) 0.221 Can we conciude that the mean travel times of the two routes are different?
