1. The daily yield for a local chemical plant has averaged 880 ton for the last several years. The quality control manager would like to know whether this average has changed in recent months. She randomly selects 50 days from the computer database and computes the average and standard deviation of the n = 50 yields as = 871 tons and s = 21 tons, respectively. Test the appropriate hypothesis using a = 0.05. A lecturer claim that the medical students put in more hours studying compared to other students. The mean number of hours spent studying per week for other students is 23 hours with a standard deviation of 3 hours per week. A sample of 25 medical students was selected at random and the mean number of hours spent studying per weeks was found to be 25 hours. Test the appropriate hypothesis using a = 0.05 to see whether the teacher's claim be 2.

HYPOTHESIS TESTING The daily yield for a local chemical plant has averaged 880 ton for the last several years. The quality control manager would like to know whether this average has changed in recent months. She randomly selects 50 days from the computer database and computes the average and standard deviation of the n = 50 yields as = 871 tons and s = 21 tons, respectively. Test the appropriate hypothesis using a = 0.05. 1. A lecturer claim that the medical students put in more hours studying compared to other students. The mean number of hours spent studying per week for other students is 23 hours with a standard deviation of 3 hours per week. A sample of 25 medical students was selected at random and the mean number of hours spent studying per weeks was found to be 25 hours. Test the appropriate hypothesis using a = accepted or not. 2. 0.05 to see whether the teacher's claim be
