Interpret this value of the power, then identify the value of beta and, interpret that value.
Sampleton is a small rural village in rural Brazil that has a population of 5,000 with high rates of heart disease. To identify people at risk of developing heart disease, public health workers conduct a village-wide cholesterol screening to identify everyone with high cholesterol - a risk factor for heart disease. They find that 25% of the population has "high" total cholesterol values, defined as 240mg/dL and above. If the sensitivity of the test is 90%, how many false negatives would there be in this population? [Round to the nearest whole number.
