Walt is the production manager for a group that manufactures and distributes specialty chemicals. Walt suspects his coworker Jesse might be stealing some of the output, and he randomly samples the 10 batches and obtains a mean batch size of 2474g with a standard deviation of 48g. Test at the $\alpha = 0.05$ whether there is evidence the true average batch size is less that the expected 2500g. Again, be sure to state your hypotheses, define your rejection region, give your test statistic, and state your conclusion and p-value.
