b) Routine physical examinations are conducted annually as part of a health service program for General Concrete Inc. employees. It was discovered that 8 percent of the employees need corrective shoes, 15 percent need major dental work, and 3 percent need both corrective shoes and major dental work. (a) What is the probability that an employee selected at random will need either corrective shoes or major dental work?

In a population at high risk of developing cancer, each individual is classified as: Undiagnosed (U), Positive (P), Treatment (T) or Deceased (D). There is a test for the cancer, but there are false positive and false negative test results. Each month: • Each Undiagnosed person will either test positive and move to the Positive category (10 % likelihood), return a false negative test result and Die (3 %) or return a true negative test result (87%) and remain Undiagnosed. • Each Positive person will move to the Treatment category (70 % likelihood), or move to the Undiagnosed category (30 %) because their earlier test result was a false positive. • Each person in the Treatment category will either recover and move to the Undiagnosed category (40 % likelihood), require treatment for another month (40 %), or Die (20 %).

The needle used in a hypodermic syringe has to be produced according to very strict standards. As a result, approximately 1.6% of all the needles manufactured need to be discarded for defects and other imperfections. A batch of hypodermic needles contains 160 needles. a. What is the probability that at least one of the needles in the batch will be defective? b. How many needles are expected to be discarded due to imperfections? c. What is the probability that exactly that many needles (as calculated in part (c)) in a batch will need to be discarded a. P(At Least 1 Discarded) = Round to 4 significant digits b. Expected # of Needles Discarded = Round to nearest whole number c. P(Expected # of Needles Discarded) = Round to 4 significant digits
A manufacturer wishes to estimate the accuracy of its final visual inspection process. A random sample of 180 devices is selected from production. An item is defective or “bad” if it contains at least one visually noticeable cosmetic defect. The process improvement team agrees that the sample contains 27 bad items and 153 good items. The team gives the items to a “certified” operator for inspection. The operator rejects 10 good pieces and accepts 11 bad pieces and classifies the remainder correctly. What is the probability that the inspector will reject an item? P(inspector will reject an item) = ________%. Enter value using one decimal place.
