My first proposal for a SIP project is to use public statistics to examine the relationship between poverty levels and race. I would use data on whites, blacks, Hispanics, Asians and the poverty levels of the groups. For this SIP an example of a null hypothesis is that percent of people who live below the poverty level of blacks and whites are the same, therefore the difference between the two is zero. An alternative hypothesis is that the percent of blacks who live below the poverty line is greater than zero and so the difference between the percent of blacks who live below poverty and the percent of whites is greater than zero. These hypotheses could be repeated using different races because the census provides that information.
My second proposal for a SIP project is to study the percent of blacks in Kalamazoo who live below the poverty line and the percent of whites. I would sample residents of Kalamazoo by doing cluster samples of different blocks within the city to gather original data. Similar to the first proposal, I would have a null hypothesis that two (e.g. Asians and Hispanics) rates of people who live below the poverty line are equal. My alternative hypothesis could be that Hispanics have a higher percentage poverty rate than Asians and so the difference would be greater than zero.
