Your answer is partially correct. The percentage of titanium in an alloy used in aerospace castings is measured in 51 randomly selected parts. The sample standard deviation is s = 0.365. (a) Test the hypothesis Ho: o = 0.25 versus H₁:o 0.25. Use a = 0.05. Reject Ho.

Your answer is partially correct.
The percentage of titanium in an alloy used in
aerospace castings is measured in 51
randomly selected parts. The sample
standard deviation is s = 0.365.
(a) Test the hypothesis Ho: o = 0.25 versus
H₁:00.25. Use a = 0.05.
Reject
✓ Ho.
(b) Find the best upper-bound for the P-value
for this test.
