The null hypothesis ($H_0$) typically represents a statement of no effect or no difference, which in this case is that the average weight is equal to 1.6 pounds. The alternative hypothesis ($H_1$) represents the conjecture or what is being tested, which is that the average weight is less than 1.6 pounds.
