The weight of grapefruits produced by an orchard is normally distributed, with a mean weight (μ) of 450g and a standard deviation of 50g. We randomly select a sample of 120 grapefruits from the orchard. A - Compute the standard error.  B-  What is the probability that the average weight of the grapefruits in the sample will lie between 445g and 460g? Interpret your answer.
