Small sample: Ninteen concrete blocks were sampled and tested for crushing strength in order to estimate the proportion that were sufficiently strong for a certain application. Seventeen of the 19 blocks were sufficiently strong. Use the small-sample method to construct an 80% confidence interval for the proportion of blocks that are sufficiently strong. Round the answers to at least three decimal places.. An 80% confidence interval for the proportion of blocks that are sufficiently strong is <p<
