2. A certain book manufacturing company presents the time it takes for sheets from a press to be folded, gathered, sewn, tipped on end sheets, and bound. The following data represent samples of books of two book production companies and the processing time for these jobs. The processing time refers to the time in days starting from the time the books come off the press to the time they are packed in cartons. Assume the data values came from normally distributed populations with unequal variances and use 5% level of significance. Company 1 5.45 5.38 15.25 10.54 21.25 Company 2 10.46 11.26 16.26 12.65 15.15 18.17 10.75 14.22 Is there sufficient evidence to conclude that Company 1 is more efficient than Company 2 if the processing time is a measure of efficiency? Step 1: Formulate the null and alternative hypothesis. Step 2: Specify the level of significance of the given information. Step 3: Determine the test statistic to be used and compute for the test statistic. Step 4: Establish the critical region based on a. Step 5: Make a decision and a conclusion
