![Suppose \( x \) has a distribution with \( \mu = 12 \) and \( \sigma = 10 \).
---
**(a)** If a random sample of size \( n = 31 \) is drawn, find \( \mu_{\bar{x}} \), \( \sigma_{\bar{x}} \) and \( P(12 \leq \bar{x} \leq 14) \). (Round \( \sigma_{\bar{x}} \) to two decimal places and the probability to four decimal places.)
- \( \mu_{\bar{x}} = \) [Textbox]
- \( \sigma_{\bar{x}} = \) [Textbox]
- \( P(12 \leq \bar{x} \leq 14) = \) [Textbox]
---
**(b)** If a random sample of size \( n = 64 \) is drawn, find \( \mu_{\bar{x}} \), \( \sigma_{\bar{x}} \) and \( P(12 \leq \bar{x} \leq 14) \). (Round \( \sigma_{\bar{x}} \) to two decimal places and the probability to four decimal places.)
- \( \mu_{\bar{x}} = \) [Textbox]
