If the standard deviation of a hole-diameter exceeds 0.01 millimeters, there is an unacceptably high probability that the rivet will not fit. Suppose that n = 15 and s = 0.008 millimetersIs there a strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters? Use ? = 0.01. State any necessary assumptions about the underlying distribution of the data. Find the P-value for this test Suppose that the actual standard deviation of hole diameter exceeds the hypothesized value by 50%. What is the probability that this difference will be detected by the test described in part (a)? If ? is really as large as 0.0125 millimeters, what sample size will be required to detect this with power of at least 0.8? An article in Fortune newspaper claimed that nearly half of all engineers continue academic studies beyond the B.S. degree, ultimately receiving an M.S. or a PhD. degree. Data from an article in Engineering Horizons indicated that 117 of 484 new engineering graduates were planning graduate study.Are the data from engineering Horizons consistent with the claim reported by Fortune? Use ? = 0.05 in reaching your conclusions. Find the P-value for this test.Discuss how you could have answered part (a) above by constructing a two sided confidence interval on p
