Bangladesh children tracked the washing habits of the childrens' mothers via survey to understand the relationship of these habits with childhood wasting. The data provided include responses from mothers to two items on this survey. The first variable represents a household's access to food: food secure, mildly food insecure, moderately food insecure, or severely food insecure. The second variable represents the mothers' responses when asked whether they use soap when washing clothes. Suppose the researchers wish to study a potential relationship between washing habits and food security. Use software to conduct a chi-square test for independence at a significance level of a = 0,05 to determine if there is a relationship between washing habits and food security. You may find these software manuals helpful. Determine the chi-square test statistic for the chi-square test for independence based on this data.
Based on the chi-square statistic and its corresponding P value select the statement that represents the correct conclusion for the chi-square test for independence.
A. Because the chi-square statistic is very large and the P value is greater than the significance level, there is sufficient evidence of a relationship between food security and whether mothers in Bangladesh households use soap when bathing children.
B. Because the chi-square statistic is very large and the P-value is less than the significance level, there is insufficient evidence of a relationship between food security and whether mothers in Bangladesh households use soap when bathing children.
C. Because the chi-square statistic is very large and the P-value is less than the significance level, there is sufficient evidence of a relationship between food security and whether mothers in Bangladesh bouseholds use soap when bathing children.
D. Because the chi-square statistic is very large and the P-value is greater than the significance level, there is insufficient evidence of a relationship between food security and whether mothers in Bangladesh households use soap when bathing children Source adapted from Railan M. E
