A manager wishes to see if the time [in minutes} it takes for their workers to complete a certain task will increase when they are allowed to wear ear buds at work. A random sample of 21 workers' times were collected before and after. Test the claim that the time to complete the task has increased at a significance level of or = 0.02. For the context of this problem, mg 2 unt\" mm; or c where the first data set represents after and the second data set represents before. Assume the population is normally.t distributed. Round answers to 4 decimal places. Ho:#d = U Ha:ud_>0 You obtain the following sample of data: After Before 52.1 55 23.1 60.8 31.1 40 56 51 82.4 21.4 62 46 51.6 44.4 51.6 53.3 62.1 42.2 29.5 23.8 62.4 49.3 56.9 66.9 20.2 63.2 80.4 65.4 60.1 51 26.5 52.6 25.1 64.5 95.2 84.2 43.6 46 41.1 50 81.3 80.2 1What is the critical value for this test? critical value = 1What is the test statistic for this sample? test statistic = The test statistic is... This test statistic leads to a decision to... As such, the final conclusion is that... '13:} There is not sufficient evidence to warrant rejection of the claim that the time to complete the task has increased. '3' There is sufficient evidence to warrant rejection of the claim that the time to complete the task has increased. '3' The sample data support the claim that the time to complete the task has increased. '33:? There is not sufficient sample evidence to support the claim that the time to complete the task has increased
