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?
Give answer to three decimal places
What is the critical value?
Give answer to three decimal places.
The proper conclusion is to reject H0.
A. TRUE
B. FALSE

Computing the vapor pressure
: A 2.30 L sample of O2(g) was collected over a liquid at a total pressure of 785 torr and 25°C. When the O2(g) was dried (vapor of that liquid removed), the gas had a volume of 1.86 L at 25°C and 785 torr.
