The same walk$-$in clinic took data measurements of its processing times on week$-$

ends only. Maximum times, with an upper limit of $30$ minutes, stayed the same.

However, the overall target time, $16$ minutes, and the lower limit$,5$ minutes, were

less than for a full week $($which were $20$ minutes and $10$ minutes, respectively$)$ due to

increased staff. Calculate a capability ratio and a Taguchi capability index for the data

and compare them, explaining why they are different or similar
