The 2010 census found that 13.9% of adults in the United States identified themselves as being of Hispanic origin. An opinion poll plans to interview 1500 adults at random. What are the mean and standard deviation of the sampling distribution of the proportion of individuals of Hispanic origin for samples of this size? - a. \( \mu_{\overline{x}} = 0.861 \) and \( \sigma_{\overline{x}} = 0.00893 \) - b. \( \mu_{\overline{x}} = 0.139 \) and \( \sigma_{\overline{x}} = 0.00893 \) - c. \( \mu_{p} = 0.139 \) and \( \sigma_{p} = 0.00893 \) - d. \( \mu_{p} = 0.861 \) and \( \sigma_{p} = 0.00893 \)
