3. 10 points A steel bar of length 3 m experiences extreme heat at its center, so that the temperature at coordinate x on the bar is given by $T(x) = 40 \sin (\frac{\pi x}{3}) + 50^\circ C$ where the bar sits along the interval $[0,3]$ on the x-axis. Determine the average temperature of the bar. Write the exact answer, i.e., no calculator values. To receive full credit, show your work.

Mammography is currently a controversial topic today for its ability to correctly screen and prevent an incident case of breast cancer. Suppose that the prevalence of breast cancer in a certain group of women is 0.30. Additionally, suppose researchers have determined the false positive rate for mammography screening to be 0.10, and the sensitivity of the screening test to be 0.83. A) What is the Predictive Value Positive for mammography in this hypothetical example? B) Interpret this finding. C) What can we say about the claim that mammography is currently controversial today?
