Read the following except carefully, and in each case, state the kind of analysis that is required or that can be used, and each case explain your choice. 1) A study was carried out to determine a person's income 10 years after first degree. It was found that the two biggest predictors were number of mathematic courses taken and number of credit hours worked per week during a person's nal year of school. 2) Ghanaian retirees returning to paid employment were asked why they did so. Financial considerations were mentioned by 38% of retirees, 22% dislike retirement, 19% alluded to the intrinsic rewards offered by work, 14% felt they were needed or wanted to help out, and 7% cited other considerations. To see if these percentages are consistent with residents of Greater Accra Region, a researcher survey 300 retirees who had returned to work. The reasons cited were broken down as following: 128 Financial considerations, 59 dislike retirement, 51 mentioned intrinsic rewards 3'7 felt that they were needed, and 25 cited other considerations. A researcher wants to test the claim that the percentages are the same for retiree workers in Greater Accra Region. 3) In a study on speed and stopping distance, researchers looked for a method to estimate how fast a person was travelling before an accident by measuring the length of their skid marks. An area that was focused on in the study was the distance required to completely stop a vehicle at various speeds. 4) A sample of 150 people from a certain industrial community showed that 80 people suffered from disease. A sample of 100 people from a rural community showed 30 suffered from the same disease. The researcher wants to test the claim that there is not difference between the proportion of people who suffer from the disease in the two communities. 5) Sustainability issues regarding microfinance in Ghana have become serious concern over few years. The researcher wants to examine the extent of contemporary challenges impeding the sustainability of micronance institutions, and also, to examine critical success factors that contribute to boosting the sustainability of microfinance institutions operations
