The weight for crates of eggs is normally distributed with a mean weight of 34.6 pounds and a standard deviation of 2.8 pounds.
Bingel [31]

Answer:

0.5532

Step-by-step explanation:

P( 31<X<35.7)

P(X>31)= P(Z>(31-μ)/σ)

           = P(Z>(31-34.6)/2.8)

          = P(Z> -1.2857)

P(X<35.7)= P(Z<(35.7-μ)/σ)

              = P(Z<(35.7-34.6)/2.8)

              =P(Z< 0.392857)

From z-distribution table

P(Z< -1.29)= 0.09853

p(Z< 0.39) = 0.65173

P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)

                   = 0.65173- 0.09853

                  =0.5532
