X2 Independence: Grades or Relationships? ANo relevant conclusion can be made because the data is not normally distributed.Since the p-value is greater than the significance level of a = 0.05, there is sufficient evidence toВsuggest relationship status and overall letter grade are independent.Since the p-value is greater than the significance level of a = 0.05, there is sufficient evidence toCsuggest relationship status and overall letter grade are dependent.Since the p-value is greater than the significance level of a = 0.05, there is insufficient evidence tosuggest an association between relationship status and overall letter grade.Since the p-value is greater than the significance level of a =0.05, there is sufficient evidence tosuggest an association between relationship status and overall letter grade. A student wondered if there was an association between relationship status and overall letter grade (based on gradepoint average) at her high school. She used a stratified random sample to select 20 students within each letter grade.The information is displayed in the table below.Letter GradeIn a relationshipNot in a relationshipTotalA812201120C1372010102061420Total4852100Ax test of independence was conducted to determine whether the data above provides convincing evidence of anassociation between relationship status and overall letter grade.
