The following data are randomly collected from three major traffic routes. The entries in the table are driving times in minutes on the these routes. Route 1 | Route 2 |Route 3 62 56 58 67 59 62 62 56 57 64 56 57 64 50 57 62 61 62 61 61 58 63 57 57 63 61 57 55 57 58 57 57 57 59 56 59 59 57 56 56 58 57 58 56 57 A One-Way ANOVA test was conducted at a 0.01 level of significance. The results are shown below. Note that some values in the table might be in scientific notation. Say, 1.65E-07 means 1.65x10" or 0.000000165.

On average, the driving times on the major traffic routes are not the same. O For 0.01 level of significance the ANOVA test shows the sample means and the sample variances, but fails to answer the question whether different traffic routes affect the average driving times. Probably, the researcher should increase the sample sizes. O For 0.01 level of significance the ANOVA test is unable to give a positive or a negative answer to the question whether different traffic routes affect the average driving times.
