Several studies have shown evidence of a relationship between geographic location and the prevalence of washing with soap. A 2017 Raihan et al. study investigated the differences between soap usage in rural and urban areas of Bangladesh. The data provided in the file represent survey responses from 10,478 Bangladesh residents, labeled as rural or urban, when asked whether they wash their hands with soap before eating. Suppose the researchers wish to determine if the proportion of Bangladesh residents who wash their hands with soap before eating is significantly larger in urban areas compared to rural areas. Use software to conduct a ‑test for the difference of two proportions to answer the researchers' question. Do not use a continuity correction for this test.
Give the values of the ‑statistic, , and -value, , for this test. Please give precise to three decimal places and to five decimal places.

=
Complete the sentence to state how the researchers should correctly interpret the results of the test at the =0.05 level.
Because
