A manufacturer of nickel-hydrogen batteries randomly selects 100nickel plates for test cells, cycles them a specified number oftimes, and determines that 14 of the plates have blistered.
z = 1.33
p- value = 0.0913
(b) If it is really the case that 16% of all plates blisterunder these circumstances and a sample size 100 is used, how likelyis it that the null hypothesis of part (a) will not be rejected bythe 0.05 test? (Round your answer to four decimal places.)

(c) How many plates would have to be tested to have?(0.16) = 0.10 for the test of part (a)? (Round youranswer up to the next whole number.)
