I need help with number 5 only please!

Sex-role stereotyping - The article "A Cross-Cultural Content Analysis of Sex-Role Stereotyping in Television Advertisements" compares sex-role stereotyping in British and New Zealand television advertisements. One of the coding or classification procedures involved the Location where the central figures in the advertisement were depicted. The researchers were interested in determining whether there is an association between Sex of the central figures and Location where they are depicted in the advertisement. The table below summarize the observed data for Great Britain, consistent with the article mentioned above Male Female Total Occupationa Domestic 18 19 37 14 37 51 Leisure 45 19 64 11 | 22 174 Elsewhere 11 Total 88 86 Researchers want to conduct a hypothesis test using the hypotheses: Hg: There is no relationship between the variables Sex and Location.
