The appropriate statistical test for this scenario is the chi-square test for independence, also known as the 11ebc114_128e_d7b2_8acb_4979d8d055c4_TB8562_11 test. This test is used to determine if there is a significant association between two categorical variables, in this case, the gender of the spokesperson and the viewer's ability to identify the product advertised. The appropriate test for this scenario would be the chi-square test for independence, which examines whether the variables of brand awareness and gender of spokesperson are dependent or independent. Choice B is not appropriate as it is for comparing multiple proportions. Choices C and D are not appropriate as they are both non-parametric tests for independent populations, which are not applicable in this scenario.
