A Manufacturer Of Nickel Hydrogen Batteries Randomly Selects 100 Nickel Plates For Test Cells Cycles Them A Specified N 1 (43.28 KiB) Viewed 106 times

A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 11 of the plates have blistered. (a) Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances? State and test the appropriate hypotheses using a significance level.05. O HOP10 versus Hp 10 OHp<10 versus H,p=10 OH :p= 10 versus Hp.10 Hp=10 versus Hp > 10 OH, :p> 10 versus H,p=10 Test these hypotheses (Give 2 to 2 decimal places and the P-value to 4 decimal places.) 2 = P-value = In reaching your conclusion, what type of error might you have committed? type I type II no possible errors O not enough information (b) if it is really the case that 13% of all plates blister under these circumstances and a sample size 100 is used, how likely is it that the null hypothesis of part (a) will not be rejected by the.os test? (Give answer accurate to 3 decimal places.) Answer this question for a sample size of 200. (Glve answer accurate to 3 decimal places.) (c) How many plates would have to be tested л= have B(0.13) = 10 for the test of part (a)? (Exact answer required.)
