Researchers Are Investigating The Properties

Researchers are investigating the properties of a test for hypertension. Suppose that 84% of hypertensives and 23% of nonhypertensives are classified as hypertensive by an automated blood-pressure machine. Suppose that 20% of the population is hypertensive. From the given data we can create the table as follows,Question is how can we create this table. Well 1st of all 20% of the population is hypertensive so assuming 500 is the population size 100 would be hypertensive and 400 would be not hypertensive.Now 84% of hypertensives and 23% of nonhypertensives are classified as hypertensive by the test so 84 out of 100 hypertensive will be positive and 92 out of 400 non hypertensive would be positive. Thus the table.a) Find the value of the SENSITIVITY. Please give your answer to 2 decimal places. So,Sensitivity = 84/(84+16) = 0.84b) Find the value of the SPECIFICITY. Please give your answer to 2 decimal places. Specificity = 308/(92+308) = 0.77c) Find the value of PREVALENCE. Please give your answer to 2 decimal places. Prevalence = 0.20 ; as 20% of the population is hypertensive.d) What is the probability of a false positive test? Please give your answer to 2 decimal places. False positive
