Answer: The required lifetime value is 11.27.
Step-by-step explanation:
Since we have given that
Mean value = 11 hours
Standard deviation = 1 hour
The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.
So, α = 0.95, z= 1.645
n = 9
So, the lifetime value would be
![x=\mu+z\times \dfrac{\sigma}{\sqrt{n}}\\\\x=11+1.645\times \dfrac{1}{\sqrt{36}}\\\\x=11+1.645\times \dfrac{1}{6}\\\\x=11.27](https://tex.z-dn.net/?f=x%3D%5Cmu%2Bz%5Ctimes%20%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5Cx%3D11%2B1.645%5Ctimes%20%5Cdfrac%7B1%7D%7B%5Csqrt%7B36%7D%7D%5C%5C%5C%5Cx%3D11%2B1.645%5Ctimes%20%5Cdfrac%7B1%7D%7B6%7D%5C%5C%5C%5Cx%3D11.27)
Hence, the required lifetime value is 11.27.
