Comment: to prepare for the nal exam, you should study these problems, the homework from chapters 26 - 28, as well as reviewing the material from quizzes 1 4. The nal exam will be comprehensive, but with an emphasis on untested material: chapter 26, exercise set f, problems 4 and 5. H0: the average amount of milk in the daily run of half-gallon cartons is 64 ounces. The test statistic here is t = (observed average) (h0-expected average) The p-value is estimated by looking in the row for 24 degrees of freedom in the t-table in the textbook. The area to the right of t = 2. 78 is between 1% and 0. 5% (because 2. 49 < 2. 78 < 2. 80). This is a two-tailed test, because we don"t have an expected direction for the di erence a priori, it could be positive or negative.
