The null hypothesis (H0) represents a statement of no effect or no difference, which in this case is that the delivery time is 30 minutes or less (u ≤ 30). The alternative hypothesis (Ha) is what the people on the opposite side of town believe, which is that it will take longer than 30 minutes (u > 30).
