For 1-10. A factory has a machine that dispenses 75 ml of fluid in a bottle. An employee believes the average amount of fluid is not 75 mL. Using 35 sample, he measures the average amount dispensed by the machine to be 70 ml with a standard deviation of 5. 1-2. State the null hypothesis A. =75 mL B. # 75 mL C. =70 mL D. # 70 mL 3-4. State the alternative hypothesis A. =75 mL B. # 75 mL C. =70 mL D. # 70 mL 5-10. At a 90% confidence level, is there enough evidence to support the idea that the machine is not working properly.
