Respuesta :

Answer: A bag can weigh 13.77 ounces and not need to be repacked.

Step-by-step explanation:

Since we have given that

Mean = 12.08 ounces

Standard deviation = 1.03 ounces

Bags in the upper 5% are too heavy and must be repackaged.

Using the standard normal table.

z = 1.645

So, [tex]X=\mu+z\sigma\\\\X=12.08+1.645\times 1.03\\\\X=13.77\ ounces[/tex]

Hence, A bag can weigh 13.77 ounces and not need to be repacked.
