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. The power of the test would increase if the sample size is increased
b.ß = 0.30
Indicate the parameter of interest
Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 milimeter?
Use a-0.05. Perform a hypothesis test. Hco-0.0001 vs. H. :o >0.001
C. Bz0.18
Suppose that the achual standard deviation of hole diameter excoods the hypothesized value by 50%. What
is the probubility that this difference will be detected by the test deseribed in part (a
d. Variance of the hole diameter
Use the OC curve below in determining B
e. The power of the test would decrease if the sample size is increased
L00
f. Reject Ho. There is evidence to conclude that the true variance exceeds
0.0001 at a = 0.05
g. Fail to reject Ho. There is insufficient evidence to conclude that the true
variance exceeds 0.0001 at a = 0.05
