Using two tail't' test find the value of test statistic as well as interpret the result
describe Clark Heter is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the afternoon shift than on the day shift. A sample of 54 day-shift workers presented that the mean number of units produced was 345, with a standard deviation of 21. A sample of 60 afternoon-shift workers displayed that the mean number of units produced was 351, with a standard deviation of 28 units. At the .05 consequence level, is the number of units produced on the afternoon shift larger?
