Screws Inc. has asked for assistance in determining whether the manufacturing process is operating correctly. When the process is operating properly, it produces screws whose weights are normally distributed with a population mean of 5 grams and a population standard deviation of 0.1 grams. The manager wishes to know if the recent change to a new materials supplier has lowered the weight of the screws. In a random sample of 16 screws, the sample mean weight is 4.962 grams. Is there enough sample evidence to conclude that lower weight screws are now being produced? Use a significance level of 5%. Question 7 options: The p-value is 0.1286 , and we fail to reject the null hypothesis. The p-value is 0.0643, and we fail to reject the null hypothesis. There is not enough evidence to support H1 that the weight is lower. The p-value is 0.1286 , and we accept the alternative hypothesis that ,yes, the screws appear to have a lower weight. The p-value is 0.0643, and we reject the null hypothesis. None of these answers are correct
