**Coffee Consumption Statistics: Educational Module** The National Coffee Association reported that 65% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed. **Part 1 of 6** (a) **Find the mean \(\mu_{\hat{p}}\).** - The mean \(\mu_{\hat{p}}\) is \(0.65\). **Alternate Answer:** - The mean \(\mu_{\hat{p}}\) is 0.65. <img src="checked.png" alt="Correct answer check mark" width="20" height="20"> --- **Part 2 of 6** (b) **Find the standard deviation \(\sigma_{\hat{p}}\).** - The standard deviation \(\sigma_{\hat{p}}\) is \(0.0318\). **Alternate Answer:** <img src="checked.png" alt="Correct answer check mark" width="20" height="20">
