A randoms sample of 21 workers' times were collected before and after. Test the claim that the time to complete the task has decreased at a significance level of a 001. For the context of this problem, μ-: μ'h'-me, where the first data set represents after and the second data set represents before. Assume the population is normally dastributed. Round answers to 4 decimal places You obtain the following sample of data After Before 50.7 40 4.3 364 50.7 50.3 64 57.9 59 44.7 543 36.3 - 61.8 513 595 33.1478 50 53.4554 51 58 30.6 49.1 68 65 53.8 53.653.1 58.9 55.5 50.1 47946.3 58 6 1611 492 What is the critical value for this test? critical value What is the test statistic for this sample? test statistic The test statistic ss.. Select an answer This test statistic leads to a decision to Select an anawer As such, tbe final conclusion is that There is not sufficient sample evidence to support the claim that the time to complete the task has decreased ace

The claculations are given after the Hypothesis Testing From the data, Mean of the differences() = -7.338 and Std Deviation of differences (sd) = 11.720 The degrees of freedom (df) = n - 1 = 21 - 1 = 20 _______________________________________________.. view the full answer
