c. Conduct the test in part b using α = .05. Interpret your results in the context of the problem. 3. A couple of decades ago, two researchers sampled private sector and public sector organizations in Australia to study the planning undertaken in their information systems departments. The researchers asked each sample organization how much it had spent on information systems and technology in the previous fiscal year as a percentage of the organization’s total revenues. The results are reported in the table below. Private Sector
Public Sector 2.58% 5.40% 5.05 2.55
.05 9.00 2.10 10.55 4.30
1.02 2.25 5.11 2.50 12.42 1.94
1.67 2.33 3.33 a. Do the two sampled populations have identical probability distributions or is the distribution for public sector organizations in Australia located to the right of Australia’s private sector firms. Test using α = .05. b. Is the p-value for the test less than or greater than .05. Justify your answer.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
