There hаve been cоmplаints thаt the manhоle cоvers in Sandcastle City are defective and falling into the sewers, leaving holes in the ground. The Sandcastle City government believes that only 4% of their manhole covers are defective, but they intend on doing a study to confirm this. If they are to be 95% confident that their results are within 1% of the actual defective percentage, how many manhole covers need to be sampled?
