# Question

A manufacturing company produces a metal rod. Use the Excel output shown here to describe the weight of the rod. Interpret the probability values in terms of the manufacturing process.

Normal Distribution

Mean = 227 mg.

Standard Deviation = 2.3 mg.

x Value ..... Probability < x Value

220 ....... 0.0012

225 ....... 0.1923

227 ....... 0.5000

231 ....... 0.9590

238 ....... 1.0000
