A farmer uses a lot of fertilizer to grow his crops. The farmer's manager thinks fertilizer products from distributor A contain more of the nitrogen that his plants need than distributor B's fertilizer does. He takes two independent samples of four batches of fertilizer from each distributor and measures the amount of nitrogen in each batch. Fertilizer from distributor A contained 23 pounds per batch and fertilizer from distributor B contained 18 pounds per batch. Suppose the population standard deviation for distributor A and distributor B is four pounds per batch and five pounds per batch, respectively. Assume the distribution of nitrogen in fertilizer is normally distributed. Let and represent the average amount of nitrogen per batch for fertilizers A and B, respectively. Which of the following is an appropriate p-value? 0.0594 0.0847 0.0896 0.1184 The Department of Education would like to test the hypothesis that the average debt load of graduating students with a bachelor's degree is equal to $17,000. A random sample of 34 students had an average debt load of $18,200. It is believed that the population standard deviation for student debt load is $4,200. The a is set to 0.05. The confidence interval for this hypothesis test would be [$14,118.9, $19,881.2] [$14,839.1, $19,160.9] [$16,279.7, $17,720.3] O [$16,788.22, $19,611.78]
