Answer 1

Given Data :

Total = 343

292 people were randomly selected

Conditional distribution of the variable "income bracket" for Republicans.

From the contingency table the income Bracket for republican

	Low	Middle	High	Total
Republican	54	46	48	148

Conditional Distribution of the variable $\chi$

$\chi _{low} = \frac{low}{total} * 100$

$\chi _{low} = \frac{54}{148} * 100 = 36.5$

X _low = 36.5%

$\chi _{middle} = \frac{middle}{total} * 100$

$\chi _{middle} = \frac{46}{148} * 100 = 31.1$

X_middle = 31.1%

$\chi _{high} = \frac{high}{total} * 100$

$\chi _{high} = \frac{48}{148} * 100 = 32.4$

X_high = 32.4%

Hence option c is correct

Low : 36.5%

Middle = 31.1%

High = 32.4%
