Sampleton is a small rural village in rural Brazil that has a population of 5,000 with high rates of heart disease. To identifypeople at risk of developing heart disease, public health workers conduct a village-wide cholesterol screening to identifyeveryone with high cholesterol - a risk factor for heart disease. They find that 25% of the population has "high" total cholesterolvalues, defined as 240mg/dL and above.If the sensitivity of the test is 90%, how many false negatives would there be in this population?
