The activities, their predecessors, and their respective time estimates are presented here: Activity Designation Immediate Predecessor Time in Days Break down both machines A None 3 Clean machine 1 B A 3 Clean machine 2 C A 3 Re-set machine 1 D B 4 Re-set machine 2 E C 2 Re-calibrate both machines F D and E 1 Final test G F 1 Using CPM, which activities have slack in this project

Acompany is developing a new high­performance wax for cross country ski racing. in order to justify the price marketingwants, the wax needs to be very fast. specifically, the mean time to finish their standard test course should be less thanseconds for a former olympic champion. to test it, the champion will ski the course 8 times. the champion's times(selected at random) are 59.9 61.9 48.8 52.2 46.6 45.3 50.6 and 41.1 seconds to complete the test course. complete parts a and b below. a) should they market the wax? assume the assumptions and conditions for appropriate hypothesis testing are metfor the sample. assume=0.05. what are the null and alternative hypotheses? choose the correct answer below. b) suppose they decide not to market the wax after the test, but it turns out that the wax really does lower the champion'saverage time to less thanseconds. what kind of error have they made? explain the impact to the company of such anerror.

Which are the best examples of costs that should be considered when creating a project budget?
