A poll reported that 67% of adults in a certain country believe that organic produce is better for health than conventionally grown varieties. Assume the sample size was 1000 and that the conditions for using the CLT are met. Complete parts (a) through (d) below. a. Find and interpret a 95% confidence interval for the proportion of adults in the country who believe organic produce is better for health. The 95% confidence interval for the proportion of adults in the country who believe organic produce is better for health is (0.641, 0.699). (Round to three decimal places as needed.) Interpret this interval. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals rounded to three decimal places as needed.) A We are 95% confident that the population proportion of adults in the country who believe organic produce is better for health is between 0.641 and 0.699 OB. There is a % chance that the sample proportion of adults in the country who believe organic produce is better for health is between and OC. There is a % chance that the population proportion of adults in the country who believe organic produce is better for health is between and OD. We are % confident that every sample proportion of adults in the country who believe organic produce is better for health is between and b. Find and interpret an 80% confidence interval for this population parameter. The 80% confidence interval for the proportion of adults in the country who believe organic produce is better for health is (.)- (Round to three decimal places as needed.)
