Can anyone help with this type of question? A hospital director is told that 71% of the treated patients are insured. The director wants to test the claim that the percentage of insured patients is more than the expected percentage. A sample of 340 patients found that 255 were insured. At the 0.02 level, is there enough evidence to support the director's claim?
