Hey I have a question that I found in a textbook for some practice before a test, but there aren't any solutions for it. I'm pretty sure it's related to testing a hypothesis, but I'm not sure.
If anyone can point me into the right direction of solving this that would be great.
Q1: Five soft drink bottling companies have agreed to implement a time management program in hopes of increasing productivity (measured in cases of soft drinks bottled per hour). The number of cases of soft drinks bottled per hour before and after implementation of the program are listed below.
Company # 1 2 3 4 5 Before 500 475 525 490 530 After 510 480 525 495 533
Test at $\alpha$ = .05 if the time management program is efficient in increasing the productivity.
