A mаnufаcturing cоmpаny wants tо determine whether twо different production task methods have the same population mean completion time. Set the null hypothesis based on the assumption that method 1 and method 2 have the same population mean completion time and challenge it in the alternative hypothesis. A simple random sample of six workers is selected, and the pair of data values ( x 1 a n d x 2 ) for the production task completion time in minutes using methods 1 and 2 are recorded. Therefore, a variable difference d= x 1 - x 2 . The values of the difference(d) for the six workers are 0.6, -0.2, 0.5, 0.3, 0.0, and 0.6. With μ d as the population means difference, the hypotheses to a two-tailed test: H 0 : μ d = D 0 H a : μ d ≠ D 0 With the above data, the researcher concludes that there is no difference in the completion time mean between the two methods at the 0.05 significance level. Could you calculate the critical value for this conclusion? Refer to the below tables and formulas. Chi-Square distribution table 1to34.jpg t-distribution table.jpg Exam4 formulas.jpg
