Explain.(b) Construct a confidence interval with a 99% confidence level for trueaverage lifetime. You can use the following statistics if needed.Et; = 51, 240, E(x; – a)² = 10,780, 520(c) Estimate how many additional data points are needed to obtain an con-fidence interval with a half-width of 150 days or less (use the same confidence level).
