A Gallup Poll in May 2004 estimated that roughly 70% of U.S. adults are in favor of the death penalty for a person convicted of murder. A random sample of 750 U.S. adults is chosen. Let X be the number of adults (out of 750) who favor the death penalty.

1. The distribution of X is binomial. What are the values of n and p?
   
   
   
2. The mean and standard deviation of X are:
   
   • $\displaystyle \mu_{{X}}={12.55},\ \text{ }\ \sigma_{{X}}={525}$
   • $\displaystyle \mu_{{X}}={525},\ \text{ }\ \sigma_{{X}}={12.55}$
   • $\displaystyle \mu_{{X}}={525},\ \text{ }\ \sigma_{{X}}={157.5}$
