Answer:

Absolute error = 39

Percent Error = 6.10%

Step-by-step explanation:

Actual value = 639 pounds

Observed Value = 600 pounds

The formula to find absolute error is:

Absolute Error = Actual value - Observed Value

= 639 - 600

= 39

The formula to find Percent error is:

Percent Error = (Actual value - Observed Value / Actual value)*100

= (639 - 600/639)*100

= 6.10%

Step-by-step explanation:

z-score of X = 6150

$\frac{6150 - 6250}{250} = - 0.4 \\$

z-score of X = 6350

$\frac{6350 - 6250}{250} = - 0.4$

P(X<6150) + P(X>6350)

=P(z<-0.4) + P(z>-0.4)

=0.3446+0.3446

=0.6892
