Automated Manufacturing Operations Are Quite Precise But Still Vary Often With D

Automated manufacturing operations are quite precise but still vary, often with distributions that are close to Normal. The width in inches of slots cut by a milling machine follows approximately the

N(0.8750,0.0011)

N(0.8750,0.0011)

distribution. The specifications allow slot widths between 0.8725 and 0.8775 inch.

What proportion (±0.001) of slots meet these specifications?
