Have been working to figure this one out but keep getting the wrong answer.
The mean load of a container shipped by the Container Shipping Company is 2300 kg with the standard deviation of 140 kg. Compute the probability that the total weight of a shipment of 130 containers shipped by the Container Shipping Company is less than 297563 kg:
Here's what I did so far: Mean total load= 2300*130= 299000
I'm not sure what the standard deviation would be for the total load so I can't find out the Z-score to get the probability it falls within this range.
