You may need to use the appropriate technology to answer this question. A juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average. A random sample of 49 bottles is selected, and the contents are measured. The sample yielded a mean content of 11.87 ounces with a standard deviation of 0.28 ounces. (a) Formulate the hypotheses (in ounces) for a test to determine if the machine is in perfect adjustment. (Enter != for # as needed.) Ho: Ha (b) Compute the value of the test statistic. (c) Compute the p-value and give your conclusion regarding the adjustment of the machine. Let = 0.05. Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. Reject Ho. There is insufficient evidence to conclude that the machine is not in perfect adjustment. Do not reject Ho. There is sufficient evidence to conclude that the machine is not in perfect adjustment. Reject Ho. There is sufficient evidence to conclude that the machine is not in perfect adjustment. Do not reject Ho. There is insufficient evidence to conclude that the machine is not in perfect adjustment.
