A regional distribution center has been struggling to keep its on-time delivery key performance indicator (KPI). The operations director is evaluating whether their newer vendor, RapidRoute Logistics, is actually delivering faster than the long-standing supplier, FleetFirst Transport. A faster average delivery time would help the director justify reallocating more volume to RapidRoute in next year’s budget cycle.To make a data-driven call, the director samples recent delivery records from both suppliers. RapidRoute Logistics (Supplier R): Sample mean = 4.1 days Sample standard deviation = 1.4 days Sample size = 35 FleetFirst Transport (Supplier F): Sample mean = 4.5 days Sample standard deviation = 1.2 days Sample size = 32 Assume population standard deviations are unknown and unequal. Determine whether there is statistical evidence at the 95% confidence level that RapidRoute’s average delivery time is faster than FleetFirst’s. The proper test for this hypothesis test is [test]. The alternative hypothesis, H1, is [alternative_hypothesis]. The p-value for this hypothesis test is [p-value]. The correct statistical decision is to [decision].
