A magazine provided results from a poll of 764 adults who were asked to identify their favorite pie. Among the respondents, 7% chose chocolate pie. If the confidence level is 81%, use the Wald asymptotic method with continuity correction to calculate the confidence interval for the proportion of adults who identify chocolate pie as their favorite pie. Show that the normal approximation to the binomial distribution is applicable. Use the normal table and linear interpolation to determine the critical value. Enter the lower bound of the confidence interval as a percentage without the % sign. (Round your percentage to the nearest tenth.)
