The weights of some IEM students and IEC students (two kinds of IE students) before they stopped smoking and five weeks after they stopped smoking are as follows: (Data are obtained from NON- INORMAL populations!) IEC Students Student 1 2 4 5 Before 119 142 151 118 135 After 121 145 151 122 139 IEM Students Student 1 2 4 5 Before 120 142 153 114 132 138 After 125 142 156 115 135 142 At 5% level of significance, could we confidently say that IEM students giving up smoking becomes heavier than IEC students who kicks the smoking habit? What is the appropriate alternative hypothesis? (Choose the capital letter corresponding to your answer) A. HIEC < HIEM B. HIEC > HIEM C. HIEC + HIEM D. HIEC = HIEM
