The technology underlying hip replacements has changed as these operations have become more popular. Starting in 2003, highly durable ceramic hips were marketed. Unfortunately, for too many patients the increased durability has been counterbalanced by an increased incidence of squeaking. A study of 143 individuals who received ceramic hips between 2003 and 2005 reported that 10 of the hips developed squeaking. Calculate a 95% confidence interval for the true proportion of such hips that develop squeaking.
