A study investigated ways to prevent staph infections in surgery patients. The researchers examined a random sample of 100 patients admitted to various hospitals for surgery. They found that 88 of these patients tested positive for Staphylococcus aureus, a bacterium responsible for most staph infections. Construct a 95% confidence interval for the proportion of all patients admitted for surgery who are carriers of S. aureus. Round your answers to three decimal places, and use four decimal places for any interim calculations. Hint: Think about the formula for the confidence interval. How do we find Zcv? ) contains the true population proportion p We are 95% confident that the interval of all patients admitted for surgery who are carriers of S. aureus.
