Q: A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 14 of the plates have blistered. Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances using a significance level 0.05?
Let p be the true proportion of plates that blister under such circumstances. State the appropriate hypotheses.
A. H0: p < 0.10 versus Ha: p = 0.10
B. H0: p = 0.10 versus Ha: p 0.10
C. H0: p = 0.10 versus Ha: p > 0.10
D. H0: p > 0.10 versus Ha: p = 0.10
E. H0: p = 0.10 versus Ha: p < 0.10
What is the test statistic?
What is the critical value?
The proper conclusion is to reject H0.
A. TRUE
B. FALSE
