Based on the previous analysis, your team decides to focus on improving capacitor performance.

To ensure a sufficient sample, you select $50$ more boards from finished goods. Here are the

results of the capacitor measurements $($in mF$\text{'}$s$)$ from the capacitors on all $100$ of the boards sampled.

Use this information to estimate the best and worst case percent defective $($out of tolerance$)$ for these

capacitors. The upper and lower specification limits for the capacitor values are

$0\mathrm{.}400$ mF$\text{'}$s and $0\mathrm{.}650$ mF$\text{'}$s$.$
