Wax-Com Electronics Inc $$Z = \frac { 8.5 - 25 ( .5 ) } { \sqrt { ( .5 ) ( 1 - .5 ) ( 25 } } = \frac { - 4 } { 2.5 } = - 1.6$$

question 61

Multiple Choice

Wax-com Electronics Inc.claims that a certain circuit board has a median operating life of less than 20,000 hours.A random sample of 25 such circuit boards showed 8 circuit boards failing before 20,000 hours and 17 circuit boards failing after 20,000 hours.Assume the useful life of the circuit board is not normally distributed.At ? = .05,can it be concluded that the sample contradicts the company's claim? Assume the useful life of the circuit board is not normally distributed.

• A)Reject the null hypothesis.
• B)Do not reject the null hypothesis.
• \[Z = \frac { 8.5 - 25 ( .5 ) } { \sqrt { ( .5 ) ( 1 - .5 ) ( 25 } } = \frac { - 4 } { 2.5 } = - 1.6\]
