In an effort to cut costs and improve profits, many U.S. companies have been turning to outsourcing. In fact, according to Purchasing magazine, 54% of companies surveyed outsourced some part of their manufacturing process in the past two to three years. Suppose 555 of these companies are contacted. Appendix A Statistical Tables a. What is the probability that 337 or more companies outsourced some part of their manufacturing process in the past two to three years? b. What is the probability that 286 or more companies outsourced some part of their manufacturing process in the past two to three years? c. What is the probability that 49% or less of these companies outsourced some part of their manufacturing process in the past two to three years? (Round the values of z to 2 decimal places, e.g. 15.25. Round the intermediate values to 4 decimal places, e.g. O.2513. Round your answers to 4 decimal places, e.g. 0.2513.) а. b. С.
