According to the American Diabetes Association (www.diabetes.org), 46.2% of Americans aged 60 years or older had diabetes in 2007. A recent random sample of 400 Americans aged 60 years or older showed that 52 of them have diabetes. Using a 5% significance level, perform a test of hypothesis to determine if the current percentage of Americans aged 60 years or older who have diabetes is higher than that in 2007.
