What are the critical path activities? 2. What is the expected completion time for the project (#of weeksi? 3. What are the variance and standard deviation for the critical path? 4. What is the probability that the project can be completed in more than than 26 weeks? Be sure to enter your answers as follow For [11: show the sequence of critical path activities letters For 12: show the answer is of weeks. For lal: must show the variance of the critical poth standard deviation For (41: show the probabilty of completing the project within 26 weeks. Once you find the score value, you need to reference Appendix B to determine the probability. PT>-20)
