A growing body of studies challenges conventional assumptions that genetics or cultural differences lead some students - such as indigenous or girls - to do poorly on standardised academic tests and other academic performances. To examine the phenomenon associated with "stereotype threat", researchers gave 47 randomly selected indigenous students a standardised test, asking students to indicate their ethnicity before taking the test (First Week). In the second week, students were given the same test but this time without revealing their race (Second Week). On a 100-point scale, students' test scores were recorded in the EXCEL fileStandardisedTests.xlsx. Use EXCEL and an appropriate hypothesis test to help researchers to answer the following research question.
