A hospital wants to construct a 95% confidence interval for the proportion of all American Adults who have given blood in the last three years. a. What is the point estimate of the proportion of American Adults that have given blood in the last three years? Round to three decimal places. [answera] b. Does the sample meet the conditions to calculate the confidence interval for the proportion? [answerb] because the sample is random, the sample is less than 5% of the population and [answerc]. c. Use the appropriate formula to find the margin of error, rounded to three decimal places. Remember to round off only at the end. [answerd] d. Using the margin of error and point estimate from the above questions, find the 95% confidence interval for the proportion of American Adults who have given blood in the last three years. Round to three decimal places. Choose the best answer. [answere]
