An employee of a small software company in Minneapolis bikes to work during the summer months. He can travel to work using one of three routes and wonders whether the average commute times (in minutes) differ between the three routes. He uses each route for one week and records the commute times. The sample information is in the accompanying data file. Click here for the Excel Data File a-1. Construct an ANOVA table. (Leave no cells blank. Round "SS" and "MS' to 2 decimal places, and "P" and "p-value" to 3 decimal places.) SS dr MS F p-value ANOVA Source of Variation Between Groups Within Groups a-2. At the 1% significance level, do the average commute times differ between the three routes. Assume that commute times are normally distributed Yes, since the p-value is less than significance level. Yes, since the p-value is not less than significance level, No, since the p-value is less than significance level No, since the p-value is not less than significance level. b. Use Tukey's HSD method at the 1% significance level to determine which routes' average times differ. (You may find it useful to reference the table. If the exact value for at - cis not found in the table, use the average of corresponding upper & lower studentized range values. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Confidence interval Do the average times differ?
