For a particular brand of TV picture tube, it is known that the mean operating life of the tubes is μ = 9000 hours with a standard deviation of σ = 500 hours. Determine the expected value and standard error of the sampling distribution of the mean given sample size of n = 25. Interpret the meaning of the computed values.

\n" ); document.write( "expected value = mean = 9000
\n" ); document.write( "standard error of sampling dist = 500/sqrt(25) = 100
