\text{Part 1 of 6} \text{(a) Find the mean } \mu_{\hat{p}}.
\text{The mean } \mu_{\hat{p}} \text{ is } 0.65.
\text{Part 2 of 6} \text{(b) Find the standard deviation } \sigma_{\hat{p}}.
\text{Part 6 of 6} \text{(f) Using a cutoff of } 0.05, \text{ would it be unusual if less than } 66\% \text{ of people in the sample were in debt?}
\text{It (Choose one) } \nabla \text{ be unusual if less than } 66\% \text{ of the people in the sample were in debt, since the probability is } \square.

Studdy Solution
