**Coffee Consumption Study** The National Coffee Association reported that 63% of U.S. adults consume coffee daily. A random sample of 250 U.S. adults is selected to explore this further. Ensure that all answers are rounded to at least four decimal places as needed. **Part 1 of 6** (a) **Finding the Mean (\(\mu_{\hat{p}}\))** - The mean \(\mu_{\hat{p}}\) is calculated as 0.63. **Alternate Answer:** 0.63 **Part 2 of 6** (b) **Finding the Standard Deviation (\(\sigma_{\hat{p}}\))** - The standard deviation \(\sigma_{\hat{p}}\) is calculated as 0.0305. **Alternate Answer:** 0.0305 These calculations provide crucial insights into coffee consumption patterns among U.S. adults, using statistical measures to offer clarity and precision.
