Let X... We observe X=9 out of n=15. Is the battery more likely to last more than 5 years?
Please see the attached file for the fully formatted problems.
Ho: p = 0.5 vs.
Ha : p > 0.5
ii. p^ = X/n = 9/15 = 0.6
we compute Standard error by
SE = SQRT ...
Hypothesis Testing, Test Statistics and Rejection Area are investigated. The solution is detailed and well presented.
