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-NORMAL populations!) IEC Students Student 1 3 4 5 Before 119 142 151 118 135 After 121 145 151 122 139 IEM Students Student 2 3 4 6 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? Perform the appropriate hypothesis test. What statistical test should be used? O Rank Sum Test O Sign Test O Signed Rank Test O Kruskal Wallis Test O Runs Test

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
