Answer 1

Answer to question 1)

Correct option : option A- Male is categorical with two categories. Its variable coding rule is that 1's represent males and 0's represent females.

Reason: " male " is a categorical variable because often because in the table, 1's represent that the student is a male and 0's represent that the student is a female. Also categorical data analysis involves two factors: presence or absence of the qualitative variable under study.

Answer to question 2)

Correct option:-option A- It does make sense. If the numbers are added then the sum is the number if males.

Reason:-since male is a categorical variable, if we sum up the categorical variable male then the sum is definitely the number of males.
