A report from 2026 claimed 22% of Americans over the age of 5 speak more than one language. It is believed that the actual percentage is lower than this. In a random sample of 244 Americans over the age of 5, 49 spoke more than one language. Determine the value of test statistic and p-value associate with this test. (Round both to four decimal places.) test statistic = [z] p-value = [p]

Read DetailsAn education researcher wants to determine if there are any differences in students’ learning using a traditional lecture-based method versus a project-based learning approach. Students are randomly assigned to one of the two groups. At the end of the semester, all students take the same standardized math test (scored on a 100 point scale) to measure their learning. What type of study is involved in this scenario?[a] What is the explanatory variable for this study?[b] What is the response variable for this study?[c] What hypotheses should be tested?H0: [d1]Ha: [d2] What type of test is needed for this scenario?
