A shipping pallet holds 10 boxes. Each box holds 300 parts of different types. The part weight

A shipping pallet holds 10 boxes. Each box holds 300 parts of different types. The part weight is normally distributed with a mean of 1 lb and a standard deviation of 0.2 lb.

a. Compute the mean and standard deviation of the pallet weight.

b. Compute the probability that the pallet weight will exceed 3015 lb.
