A college student wants to determine whether the stress level of a student is associated to his/her body mass index (BMI). She randomly selected 80 students and determine their stress level and BMI. The data obtained is summarized in the table below. BMI Stress Level Total Normal Not Normal Low 20 31 51 Hight Total 15 14 29 35 45 80 Suppose the value of the appropriate test statistic is 1.1754, which of the following statement(s) is(are) TRUE? I. The expected number of students who have high stress level and whose BMI is NOT normal is 16.3125 II. There is a low association between the stress level of a student and his/her body mass index (BMI). Both I and II O Neither I nor II
