A chest phantom was implanted with different sizes and types of nodular lesions and was imaged with a new X - ray scanner. Let us assume that there are 156 radiographs of the chest phantom screened for detection of nodular lesions. The radiographs showed 44 lesions, out of which four lesions were verifi ed to be false. The radiographs also missed three lesions that could not be seen by an observer. Compute accuracy, sensitivity, and specifi city of the X - ray scanner in imaging nodular lesions in the chest.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
