Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, and spine. The Center for Disease Control (CDC) indicates that about 43% of cases of tuberculosis in the lungs, 30% in the spine, and 27% in the kidneys. A TB researcher gathered her own data with a sample of 354 adults in the Greater Philadelphia aera (See table below for counts of each tuberculosis cases. Which one of the following statements is INCORRECT? (Alpha level is set at 0.05.) TB in TB in TB in Lungs Spine kidneys Observed 134 132 88 Cases The null hypothesis of a chi-square goodness-of-fit test is p1-43%, p2=30%, p3-27%. The decision should be to fail to reject the null hypothesis. One can conduct a chi-square goodness-of-fit test because the condition, Min(p1'n, p2'n, and p3*n] is greater or equal to 5, is met. O The expected frequency of TB in Spine is 106.2 cases. O The obtained chi-square is 9.1.
