A Bethlehem brewery wishes to ensure that an average of exact 12 ounces of beer is used to fill each bottle. To analyze the accuracy of the bottling process, the bottler takes a random sample of 36 bottles. The sample mean weight and the sample standard deviation of the bottles are 11.80 ounces and 0.8 ounces, respectively. (a) State the null and the alternative hypotheses for the test. (2 points) (b) Compute the test statistic. (2 points) (c) At a = 0.05, solve using the critical value approach. (2points) (d) At a = 0.05, solve using the p-value approach. (2 points) (e) What do you conclude (using either approach)? (2 points) A B E S'S U S X2 E E 9 C. 86 88
