Answer to Problem 40PT4

  $(b)\frac{299}{494}\ne \frac{397}{850}$

Explanation of Solution

Given:

  

The Republican and favoring the death penalty are independent if the proportion of republicans among those who favor the death penalty is the same as the proportion of Republicans in the entire sample.

Therefore, the proportion of Republicans among those who favor the death penalty is,

  $\frac{299}{494}=0.6053$

The proportion of Republicans in the entire sample is,

  $\frac{397}{850}=0.4671$

Here, these both proportions are different which indicate that Republican and favoring the death penalty are not independent.
