1) A manufacturer of cereal claims that the mean weight of aparticular type of box of cereal is 1.2 pounds. A random sample of71 boxes reveals a sample average of 1.186 pounds and a samplestandard deviation of .117 pound. Using the .01 level ofsignificance, is there evidence that the average weight of theboxes is different from 1.2 pounds?

Is the test statistic for this test Z or t?
