4. Lifetimes of VLSI chips manufactured by a semiconductor manufacturer are approximately normally distributed with mean 5 x 106 h, and standard deviation 5 x 105 h. A computer manufacturer requires that at least 95% of a batch should have a lifetime greater than 4 x 10. Will the deal be made? Compute the probability mathematically using Z-tables and also using R. 4.
