The capability score of the supplier is 0.6667

Step-by-step explanation:

to calculate the capacity of the supplier we will use the following formula

= (USL-LSL) / 6 * Est. Dev

we replace with the data

= (95.5-94.5) / (6 * 0.25)

we make the corresponding calculation

= 1 / 1.5

we get the following result

= 0.6667
