filed by California and several other states, aiming to stop the curreem The Supreme Court just heard a case California a administration from including a question about citizenship on the 2 question worry that including it will cause many immigrants (who 2. 2020 census. Opponents of the citizenship may be worried about their status or wary of al) to not report or to under-report their presence. Because the census ers of congressional representatives a region gets, as well as funding amounts for is used to determine the numbers repr several programs, it is extremely regardless of citizenship status To test whether the inclusion of question w including the citizenship question, was done in a region where r population was made up of previous census important that the census is an accurate count of who is living in this country f the citizenship question would cause under-reporting, a trial run of the census esearchers knew that a large percentage of the ants. For previous census forms (that did not include the citizenship urn for census forms in this region was 78%. The researchers randomly sampled ensus (which included the citizenship question) 500 households in the region, and sent each household the test c to fill out. Researchers received only 342 census forms back. You want to test the whether the proportion of trial is significantly smaller than usual, possibly due to the inclusion of the citizenship question.
