Question about sensitivity and specificity

Question 5 Your Medical Science degree goes well and eventually you become a General Practitioner. Based on all the information Not yet currently available, you estimate that the patient in your office has a one in four chance of having a particular serious answered disease. You order a diagnostic test with sensitivity of 95% and specificity of 90%. Marked out of 2.00 The result comes back positive. Based on all the information now available, the chance your patient really has the disease is closest to: Flag question Select one: O a. 75% O b. 65% O c. 85% O d. 55%Question 6 Based on all the information currently available, you estimate that the patient in your office has a one in four chance of Not yet having a serious disease.

The graph below demonstrates the distribution of serum marker levels in both healthy and diseased Marked out of populations. 1.00 Diseased Remove flag m Serum marker Compared to the blue curve, the red curves are associated with: Select one: O a. Higher sensitivity and lower specificity O b. Lower sensitivity and lower specificity O c. Higher sensitivity and higher specificity O d. Lower sensitivity and higher specificity Clear my choice
