Question

Suppose that we have two variables, sex (male or female) and handedness (right-or left-handed). We observe the values of both variables in a random sample of 100 people. Then a two-way can be used to express the relationship between these two variables, as follows (Note that this is a hypothetical dataset): For male, the percentage of right-handed person is For female, the percentage of right-handed person is Which of the following is the correct statement about the conclusion you can make about the association between gender and handedness? Left-handed male is smarter than right-handed female This is an example of Simpson paradox. Female has lower percentage of left-handed person than male. There is no relationship between gender and handedness

Explanation / Answer

Percentage of right handed peron in males is

(45/60)*100% = 75%

5.2

Percentage of right handed peron in females is

(38/40)*100% = 95%

5.3

Since percentage of right handed person in female is greater than percentage of right handed person in male so percentage of left handed person in female is less than percentage of left handed person in male . Sp option c is correct.
