The titanium content in an aircraft-grade alloy is an important determinant of strength. A sample of 20 test coupons reveals the following titanium content (in percent): 8.32, 8.05, 8.93, 8.65, 8.25, 8.46, 8.52, 8.35, 8.36, 8.41, 8.42, 8.30, 8.71, 8.75, 8.60, 8.83, 8.50, 8.38, 8.29, 8.46. The median titanium content should be 8.5%. Use the sign test with a = 0.05 to investigate this hypothesis. Match the answers. Parameter of Interest: a. Hi i =8.5 Null and Alternative Hypothesis: Hiñ ±8.5 Test Statistic: b. H H=8.5 H;u #8.5 v Reject the null hypothesis if. Conclusion: C.r- = 12 d. H; u =8.5 H:ã>8.5 e. Median Titanium content f. Fail to reject the null hypothesis. There is not enough evidence to conclude that the median of the titanium content differs from 8.5%. h.r = min (R*,R-) i. Mean of the Titanium content i. Reject the null hypothesis. The median of the titanium content differs from 8.5%.

Transcribed Image Text:The titanium content in an aircraft-grade alloy is an important determinant of strength. A
sample of 20 test coupons reveals the following titanium content (in percent):
8.32, 8.05, 8.93, 8.65, 8.25, 8.46, 8.52, 8.35, 8.36, 8.41, 8.42, 8.30, 8.71, 8.75, 8.60, 8.83, 8.50,
8.38, 8.29, 8.46. The median titanium content should be 8.5%.
Use the sign test with a = 0.05 to investigate this hypothesis. Match the answers.
Parameter of Interest:
a. Hi i =8.5
Null and Alternative Hypothesis:
Hiñ ±8.5
Test Statistic:
b. H H=8.5
H;u #8.5
v Reject the null hypothesis if.
Conclusion:
C.r- = 12
d. H; u =8.5
H:ã>8.5
e. Median Titanium content
f. Fail to reject the null hypothesis. There is not enough evidence to
conclude that the median of the titanium content differs from 8.5%.
h.r = min (R*,R-)
i. Mean of the Titanium content
i. Reject the null hypothesis. The median of the titanium content differs from
8.5%.
