Question
If the standard deviation of a nut's hole diameter exceeds 0.01 millimeters, there is an unacceptably high probability that the screw will not fit. Suppose that n = 20 and s = 0.008 millimeter. a. Reject Ho. There is evidence to conclude that the true variance exceeds 0.0001 at a = 0.05 v Indicate the parameter of interest Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeter? b Variance of the hole diameter Use a = 0.05. Perform a hypothesis test. Ho: o = 0.0001 vs. H1 : o > 0.0001 c. Bz0.18 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)? d. Fail to reject Ho. There is insufficient evidence to conclude that the true variance exceeds 0.0001 at a = 0.05 Use the OC ve below in determining B е. В3D 0.30 1.00 f.
