Question

Applications of Normal Distributions Suppose that a manufacturing facility is producing a support beam that is intended to be exactly 10 cm in length, however the beam can be as short as 9.75 cm or as long as 10.5 cm and still fulfill its purpose. Assume that the variation in beam lengths can be modeled as a Normal Distribution, and answer the following questions.

Answer 1

solution Here mean (4)=10, S.D(6)=0.25 P(meet requirements) P(Between 9.5 8 10-25 =P(9.55x510.25)=P(32-16-29)- P(x295) = '0.8 013-0.0228= 0-8185 =
