A non-invasive device is used to diagnose a disease X. The sensitivity of the device is 100% and the specificity is 30%. A patient's test results turned out to be positive. Which of the following statement is true:

		The high sensitivity of the test is enough to determine the actual test result.
		We are 100% certain that the patient has disease X.
		We are 30% certain that the patient has disease X.
		This device is more likely to give false positive results amongst patients without disease X. Therefore, we cannot be certain that the patient has disease X or not.
