Explanation not required only the answer. Thank you.
More and more restaurants allow customers to get their drinks directly from the automatic dispenser. Warren works in a company that manufactures various types of drinks dispensing machines. When the dispenser is operating well, the average amount dispensed should be 14 fluid ounces. From time to time, the dispenser needs to be checked to make sure that the amount dispensed is as set. If it is found that the amount dispensed is significantly higher or lower than 14 fluid ounces, adjustment needs to be done. In a recent visit to a client's restaurant, Warren dispensed six cups of drinks and carefully measured the amount in each cup. The mean was found to be 14.30 ounces, with a sample standard deviation of 0.18 ounces. The amount dispensed is assumed to be normally distributed. At 1% significance level, test whether the dispenser is dispensing an average of more than 14 fluid ounces. State the null hypothesis. A. 4.0825 State the alternative hypothesis. B. U 2 14 Is this a one-tailed or two-tailed test? C. population sample size is unknown State the critical value. D. True v Calculate the test value. E. population standard deviation is unknown State the decision. F. sample standard deviation is known v Justify your choice of decision in previous part. G. The test value falls in the critical region. There is enough evidence to conclude that the machine is dispensing an average of more than 14 fluid ounces. Is the statement true or H. Do not reject the null hypothesis false? 1. 1.6667 The conclusion of the test indicates that the machine does not need any adjustment. Is the statement true or false? J. 3.7469 Why do you think the standard normal distribution is not used in this hypothesis test? K. H > 14 L. Reject the null hypothesis. M. False N. HStep by Step Solution
