Medical tests. medical tests are used to indicate whether a person has a particular disease. the sensitivity of a test is the probability that a person having the disease will test positive (indicating the person has the disease, i. e., it’s the probability the test will pick up the fact that a person has the disease). the specificity of a test is the probability that a person not having the disease will test negative. a test for a certain disease has been in use for many years. based on the “track record” of this test, its sensitivity is 0.934 and its specificity is 0.968. finally, in the population, 1 in 500 people has the disease. what is the probability that a person who tests positive actually has the disease?

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
